Important Safety Instructions

1. Read and follow all warning notices and instructions marked on the product or

included in the manual.

2. This product is intended to be used with a three-wire grounding type plug - a plug

which has a grounding pin. This is a safety feature. Equipment grounding is vital to

ensure safe operation. Do not defeat the purpose of the grounding type plug by

modifying the plug or using an adaptor.

Prior to installation, use an outlet tester or a voltmeter to check the ac receptacle for

the presence of earth ground. If the receptacle is not properly grounded, the

installation must not continue until a qualified electrician has corrected the problem.

If a three-wire grounding type power source is not available, consult a qualified

electrician to determine another method of grounding the equipment.

3. Slots and openings in the cabinet are provided for ventilation. To ensure reliable

operation of the product and to protect it from overheating, these slots and openings

must not be blocked or covered.

4. Do not allow anything to rest on the power cord and do not locate the product where

persons will walk on the power cord.

5. Do not attempt to service this product yourself, as opening or removing covers may

expose you to dangerous high voltage points or other risks. Refer all servicing to

qualified service personnel.

6. General purpose cables are provided with this product. Special cables, which may be

required by the regulatory inspection authority for the installation site, are the

responsibility of the customer.

7. When installed in the final configuration, the product must comply with the applicable

Safety Standards and regulatory requirements of the country in which it is installed. If

necessary, consult with the appropriate regulatory agencies and inspection

authorities to ensure compliance.

8. A rare phenomenon can create a voltage potential between the earth grounds of two

or more buildings. If products installed in separate buildings are interconnected, the

voltage potential may cause a hazardous condition. Consult a qualified electrical

consultant to determine whether or not this phenomenon exists and, if necessary,

implement corrective action prior to interconnecting the products.

NMS communicates with its network devices using one of two diagnostic protocol modes: the

Advanced Diagnostic protocol (ADp) or the DATAPHONE II (DPII) diagnostic protocol. NMS

uses these protocol modes to collect and process diagnostic information from the network devices.

If any of the devices in an NMS diagnostic tree are DATAPHONE II devices, the modems use the

DATAPHONE II protocol. If the NMS diagnostic tree consists of all COMSPHERE devices, the

Advanced Diagnostic protocol (ADp) mode is used for device communications.

NMS communicates with the DATAPHONE II modems, the DATAPHONE II DSUs, the

COMSPHERE modems and the 3600 Series DSUs via the modem control channels ports provided

by a single Emulexr DCP/MUXI card. (For NMS hardware descriptions, refer to the

COMSPHERE 6800 Series Network Management System User’s/System Administrator’s Guide.)

The NMS communicates with the Service Restoration Control Units via the user-defined port(s) on

the IPC-1600 card installed in the NMS.

The NMS communicates with ANALYSIS NMS devices via one port on a dedicated IPC-900 card

installed in the NMS. This port is used for uploading the ANALYSIS NMS device configurations

to the NMS for alert management, and for establishing a cut-through session to the ANALYSIS

system in order to issue commands to the ANALYSIS NMS devices, to execute diagnostic tests on

these devices, and also to use remote printing capabilities.

Managing Modems and DSUs

1-36800-A2-GB20-20 January 1997

Security

Security in the network is achieved by regulating each user’s access to network devices and to

NMS commands. User access levels are assigned using the Create User Profile (crup) or Edit User

Profile (edup) commands from the Manager task.

Refer to the COMSPHERE 6800 Series Network Management System User’s/System

Administrator’s Guide for a detailed discussion on setting up user access security within the

6800 Series NMS.

Defining Profiles

NMS device, site, vendor and facility profiles are used to store information relevant to specific

devices. The contents of the profiles are described in the COMSPHERE 6800 Series Network

Management System Core Command Reference Manual. The profiles must have specific data in

them for modem support. The information required in the profiles for the modem, Data Service

Unit (DSU), Service Restoration Control Unit (SRCU), Analog Bridge (AB), and Dial Backup

Unit (DBU) is described in more detail, as follows:

Device Profiles

Device profiles contain detailed operation information about a device. The following device profile

fields should be completed for all modem, DSU, AB, and DBU devices, as indicated:

Device Address

Identifies the device’s link-level address. NMS does not allow any address that is not

unique.

For COMSPHERE devices, the link-level address is the one associated with the device’s

current protocol mode. Thus, if the device is operating in ADp mode, the address stored

should be the link-level address (long form) that is made up of each device’s

COMSPHERE network address. If the device is operating in DATAPHONE II mode, a

short form address is used. A short form address is a link-level address that is missing the

G2/G4 tributary addresses upstream of the designated device. In DATAPHONE II mode,

alarms that are reported on devices that have upstream tributaries are always identified

with short-form addresses. To properly identify incoming alarms, you must specify the

short-form address for these devices. If a long-form address is used, the alarm will be

listed as being associated with an unknown device.

Inventory state

Identifies the existing state of a device in the network.

Valid entries are as follows:

active (default) The device is being actively used in the network.

on order The device is on order from the vendor.

repair The device has been sent out for repair and is not currently in use on

the network.

stock The device is in stock, but is not currently in use on the network.

removed The device is no longer part of the customer’s inventory.

limited access The remote 3800/3900 device is active but has no link level address.

COMSPHERE 6800 Series Network Management System

1-4 January 1997 6800-A2-GB20-20

Device Type

Identifies the type of device and determines the icon to be used on the Connectivity Maps.

Device types are unique to applications. Refer to Appendix C in the COMSPHERE 6800

Series Network Management System User’s/System Administrator’s Guide for valid device

types.

Protocol mode

Identifies the protocol in which a device will run. The protocol that is used depends on the

configuration of the individual diagnostic tree. A diagnostic tree consists of the head

control device and all downstream devices connected to it diagnostically.

Valid entries are dataphone for a device on a tree running in DATAPHONE II mode, or

advanced for a device on a tree running in ADp mode.

You can change the protocol of a device using the Change Protocol Mode (chpm)

command. When you issue this command to change mode, the Protocol mode field is

updated. If the Protocol mode field is not properly set for the device, tests, commands,

and polling will not function properly. You will receive an NR (no response) message for

normal polling that is directed to a device in the wrong protocol mode.

NMS Support

Valid entries are as follows:

supported Commands can be directed to the device from the NMS and alerts are

reported back.

unsupported The device is displayed on the map but it cannot communicate with

the NMS.

Product type

Identifies the product name. Valid entries are comsphere (for 3400/4400 and 3900 Series

modems, 3600 Series DSUs, DDD modems, and 3800 Series DDD modems), dataphone

(for DATAPHONE II modems), and 3500 dsu (for 3500 Series DSUs).

Model number

Identifies the appropriate model number for the specified device type. If NMS is able to

communicate with the device, this information may be reported by the device itself. Valid

model numbers that can be entered in this field are listed in Appendix A of the

COMSPHERE 6800 Series Network Management System User’s/System Administrator’s

Guide.

Alternate mode address

Handles the conflict between short- and long-form addresses in DATAPHONE II and

ADp modes. Populate this field if you expect to change the device’s protocol mode. It is

not validated for uniqueness.

In ADp mode, short-form addressing is not valid. All devices upstream of the designated

device must be included in the link-level address. If this is not done properly, conflicts

arise when mode conversions are done: either addresses are missing (DATAPHONE II

mode to ADp mode) or addresses are there that should not be (ADp mode to

DATAPHONE II mode.)

Managing Modems and DSUs

1-56800-A2-GB20-20 January 1997

To allow the mode conversion to be done correctly, NMS uses the Alternate mode

address field. If a device is in DATAPHONE II mode, and its link-level address is in

short-form, populate this field with the long form link-level address. The alternate mode

address should be maintained along with the device’s link-level address. If the link-level

address changes, edit this field. During the mode conversion process, NMS automatically

changes the link-level address and updates this field.

System polling

Activates or deactivates polling on the control channel for a device. In ADp mode, this

field is ignored for all devices except local control modems. In DATAPHONE II mode,

extended polling to devices downstream of the local control device may be necessary in

some configurations. In this case, enter extended poll in this field and the system will

poll these devices separately.

In DATAPHONE II mode, local control devices must be in CC active mode, and devices

on extended polling must be in extended poll mode. In ADp mode, no extended polling is

used. Only local control devices are polled on the control channel.

Call Statistics:

Collect (Appears only for model# 3811 local carrier-mounted 3800 Series devices)

Valid entries are yes, no. Entering yes causes a summary to be kept of the

number of calls for a period of time.

Store call detail (Appears only for model# 3811 local carrier-mounted 3800 Series

devices)

Valid entries are yes, no. Entering yes causes the reason for disconnect to be

stored (i.e., device name, duration, speed, disconnect cause).

Site and Vendor Profiles

Site and vendor profiles are generic and do not have any modem-specific information.

These profiles are used to describe and place the site location for each device, and to

describe and store information about vendors. For additional information on these

profiles, refer to the COMSPHERE 6800 Series Network Management System

User’s/System Administrator’s Guide.

Facility Profiles

Facility profiles are used within NMS to store information on the physical connection

between devices and to allow for the representation within the network map of these

connections. For example, facility profiles can be used by the service restoration products

to represent the following types of facility connections:

• APL modem to dedicated AB

• APL modem to dedicated DBU

• APL modem to Service Restoration Carrier via an SRCU device

• AB to AB, when a second AB is being used to extend the capacity of the first

• DBU to AB

1-6 January 1997 6800-A2-GB20-20

Polling

Alarms from devices in the network are automatically reported to the 6800 Series NMS via the

polling process. The 6800 Series NMS polling process consists of two steps. First, the NMS

establishes a poll list of the local control modems, DSUs, and Shared Diagnostic Units (SDUs)

through entries in the device profiles of these local control devices or via the Acquire Modem

Control Channel Poll List (acmccpl) command. Thereafter, the NMS continuously polls each local

control device on its poll list. For a discussion of NMS poll lists, refer to COMSPHERE 6800

Series Network Management System User’s/System Administrator’s Guide.

Each control modem and DSU must then establish a poll list of its tributary devices. Tributary

devices must then establish a poll list of extended control devices. You can cause a device to

establish its poll list by executing the Acquire Poll List (acpl) or Change Poll List (chpl) command.

Also, in the case of DATAPHONE II DDD devices, each local SDU must establish a poll list of its

DDD modems. After a poll list is established, the control modem, DSU, and SDU poll each device

on its poll list. When alerts are detected by the polling of these control devices, they are reported

back to the NMS when the local control devices are polled.

To establish a modem, DSU, or SDU poll list, execute the following commands:

Acquire Poll List (acpl)

This command directs a control modem or DSU to compile a poll list automatically by

polling all allowable addresses one diagnostic level below it. A device is added to the poll

list when it responds to the poll. This command is also used to establish an SDU poll list

by polling the SDU’s serving dataset slots to determine if a DDD modem is present. If a

DDD modem responds, it is added to the SDU poll list.

Each device on the poll list has a unique address based upon its location within the

network. Refer to Appendix D of the COMSPHERE 6800 Series Network Management

System User’s/System Administrator’s Guide for more detailed information on device

addressing.

Change Poll List (chpl)

This command allows you to add or delete a device manually from a control modem’s or

DSU’s poll list, or to change a device’s polling status from active to inactive so that it is

skipped during the polling process. This command also allows you to perform the same

task with each local SDU and its DDD modems. You can use this command to add a

limited number of devices to a poll list, or to otherwise update an existing poll list.

Refer to the COMSPHERE 6800 Series Network Management System Communications Products

Support Command Reference Manual for additional information on these commands.

The Poll-Only Tributary feature is a 4400 Series Analog Private Line (APL) modem configured as

a tributary modem and used for diagnostic polling expansion (i.e., it is used to expand polling

capabilities on the network). It may be identified as Model 4434-02 or Model 4444-02 APL

modem.

The Poll-Only Tributary can poll an additional 256 devices on its DC poll list. These polled

devices may be any device that supports Paradyne’s Advanced Diagnostic protocol (ADp). For

more information on the Poll-Only Tributary feature refer to the COMSPHERE 6800 Series

Network Management System Installation and Maintenance Guide.

Protocol Modes

NMS manages devices by communicating in one of two protocols, depending on the configuration

of each individual diagnostic tree. A diagnostic tree consists of the head control device and all

downstream devices connected to it diagnostically. Each control device on the control channel,

along with all its downstream devices, represents one diagnostic network. The protocol used by a

diagnostic network is determined by the types of devices on the network. If all devices are

COMSPHERE devices, ADp protocol may be used. If any device is a DATAPHONE II type, the

DATAPHONE II protocol must be used. Different diagnostic networks on the same control

channel may operate in different protocols. When COMSPHERE devices are in DATAPHONE II

mode, some commands and functions operate differently than when the devices are in ADp mode.

The 6800 Series NMS allows you to monitor circuits and equipment in real time, to invoke

diagnostic tests, to set thresholds for alert reporting and speed changes, and to design your own

applications for the general purpose external leads.

The 6800 Series NMS diagnostic system extends outward from the local control modems to

tributary modems and beyond to downstream links. This diagnostic system transports network

control, monitoring, and testing information between devices, and between these devices and the

NMS. Several channels are used to pass the diagnostic information. These channels are described

as follows:

Control Channel (CC)

NMS uses the control channel to communicate with control devices that are located at the

head of the network tree.

Secondary Channel (SC)

Most devices incorporate a secondary channel that sends diagnostic information over the

transmission line used by the primary data system. This channel connects a control

modem with its downstream tributary modems.

Diagnostic Channel (DC)

Hardware connections between co-located devices in an extended network. The

diagnostic channel connects tributary modems to extended control modems or to other

tributary modems.

The diagnostic system is divided into two diagnostic network types according to the device family

(DATAPHONE II and/or COMSPHERE) represented in the network.

The DATAPHONE II diagnostic network is composed of all DATAPHONE II devices or of a

combination of DATAPHONE II, 3400/4400 Series devices, and 3600 Series DSUs. This type of

network operates in a DATAPHONE II diagnostic protocol mode and each device operating in this

mode must be identified by an addressing scheme that resembles the DATAPHONE II addressing

scheme.

The Advanced diagnostic network is composed of only COMSPHERE devices. This type of

network operates in the ADp protocol mode, and each device operating in this mode must be

identified by the Advanced protocol mode addressing scheme.

These networks are described in the following sections. If you migrate from one type of diagnostic

network to another, you must change the diagnostic protocol mode in which you network devices

operates, as described later in this chapter.

DATAPHONE II Diagnostic Network

The DATAPHONE II diagnostic network contains DATAPHONE II devices or COMSPHERE

devices. In this network, all COMSPHERE devices must conform to the restrictions of the

DATAPHONE II network topology when they are replacing point-to-point and multipoint circuits.

The 6800 Series NMS identifies a modem and its position in the diagnostic tree by the device’s

link-level address using the following guidelines:

• Up to three circuit links can be cascaded. (Modems do polling for up to three links.) In this

network, COMSPHERE modems must adhere to these DATAPHONE II configuration rules.

(Note that in Advanced diagnostic networks consisting of COMSPHERE APL modems,

circuits can be up to five links deep.)

• The COMSPHERE modems on the control channel in this network must have a

DATAPHONE II local address and port address as part of their link-level address. The local

address is a DATAPHONE II address used on the control channel. The port address of a

COMSPHERE device in DATAPHONE II mode is always 1.

• Each device on the same level must have a unique network address, which is known by and

stored in the modem.

When COMSPHERE circuits are present in a DATAPHONE II diagnostic network, some

functionality may be lost.

You should be aware of the following constraints:

• The 3400/4400 Series modems in DATAPHONE II mode use the following advanced

network configuration options: point-to-point or multipoint; control, standard (G4) tributary;

or DATAPHONE II outboard (G2) tributary. The G2-trib option is used only when the

modem is in the outboard tributary position.

• Execution of any multiple-link tests, such as the End-to-End test, is supported only when the

control and tributaries are of the same type.

• Some DATAPHONE II tests and commands do not execute in the same way in

COMSPHERE devices as they do in DATAPHONE II modems. Even so, a COMSPHERE

device in DATAPHONE II mode returns all results to DATAPHONE II requests in the same

format as a DATAPHONE II modem would so that they can be interpreted by the NMS.

Refer to the COMSPHERE 6800 Series Network Management System Communications Products

Support Command Reference Manual before executing tests/commands to a 3400/4400 Series

modem or to a specific port.

For more information on command execution in the two diagnostic protocol modes, refer to

Protocol Modes and Command Differences later in this section.

Advanced Diagnostic Network

The Advanced diagnostic network uses a true tree topology. (A tree is composed of point-to-point

and multipoint circuits.) Note that the circuits are not designated as outboard, backbone and

extended as in DATAPHONE II networks. In Advanced diagnostic networks, a circuit’s position is

specified by its level in the tree.

Follow these guidelines when working with Advanced diagnostic networks:

• Up to five circuit links can be cascaded in any combination of point-to-point or multipoint

circuits.

• Up to 256 local devices on each control channel can be supported by the NMS.

• Up to 32 tributary modems (multipoint drops) can be polled by a control modem on its

secondary channel.

• Up to 256 downstream devices can be polled by a tributary modem on its diagnostic

channel.

• Multipoint circuits can be installed behind multipoint circuits. (Note that in a DATAPHONE

II network, extended tail circuits are the lowest level in the diagnostic tree.)

Each COMSPHERE device on the same diagnostic, secondary, and control channel must have a

unique network address. If a control modem is connected to the NMS control channel, the network

address of the modem must be added to the NMS poll list. If the control modem is located further

downstream, its network address must be added to the upstream tributary modem’s poll list. Each

device must have a device profile in ADp mode.

NOTE

The ADp mode in which the Advanced diagnostic network operates

requires the long-form addressing scheme. Therefore, the address

of each intermediate tributary modem must be included in the

address. For more information on addressing, refer to Appendix D of

the COMSPHERE 6800 Series Network Management System

User’s/System Administrator’s Guide.

Changing Protocol Modes

As your type of diagnostic network changes, you must change the diagnostic protocol mode in

which your devices operate. When you created device profiles, you indicated a device’s link-level

address and protocol mode. Unless this information has been changed locally at a device, the

profiles have remained synchronized with the devices.

There are two ways in which the protocol mode can be changed: from the NMS or from the

device’s front panel. The method of synchronization is different for these two choices.

NOTE

The following paragraph applies to installed networks only. Although

it is possible to change the protocol mode from the front panel of a

device, you should avoid doing so. When you change protocol mode

from the front panel, an immediate address conversion occurs at the

control modem. However, the address conversion is not

automatically reflected in the 6800 Series NMS. The recommended

way to change the protocol mode of a diagnostic tree is by

executing the Change Protocol Mode (chpm) command in the 6800

Series NMS.

Certain conditions may prevent the execution of the Change Protocol Mode (chpm) command; or

may permit the execution of the command but lead to the loss of data or routines. Therefore, you

should take the following steps to prepare for conversion:

1. Review the Alternate mode address field in the device profile for every device on the

diagnostic tree. If you are moving to ADp mode (from DATAPHONE II mode), be sure

that long-form addresses appear in this field.

2. If you are moving to DATAPHONE II mode (from ADp mode), be sure that short-form

addresses are supplied in the Alternate mode address field and be sure that no device has

a network address value greater than 80. For more information on device addressing, refer

to Appendix D of the COMSPHERE 6800 Series Network Management System

User’s/System Administrator’s Guide.

3. To change information in the Alternate mode address field, execute the Edit Device

Profile (eddp) command. The COMSPHERE 6800 Series Network Management System

Core Command Reference Manual explains these commands in detail.

4. Verify that all devices on the diagnostic tree have complete, correct poll lists.

5. Verify that there are no active alerts on the network.

6. Verify that no devices are in test mode. If any devices are in test mode, abort the test or

wait until its completion before beginning the protocol conversion process.

Changing from DATAPHONE II Mode to ADp Mode

To change from DATAPHONE II mode to ADp mode, execute the Change Protocol Mode (chpm)

command from the NMS System Management window to the control modem at the head of the

tree. This modem is the only one to which you may issue this command. The NMS issues a

subnetwork abort to the control modem using the current mode address of that device. Then, NMS

determines the new link-level address of the control modem. Therefore, if the original link-level

address had been:

CC/la/pa

Where: CC = the control channel

la = the DATAPHONE II local address

pa = the port address

Managing Modems and DSUs

1-116800-A2-GB20-20 January 1997

The new address would be:

CC/na

Where: CC = the control channel

na = the Advanced Diagnostic protocol mode network address

calculated by NMS. Notice that the port address is deleted.

NOTE

If the new link-level address conflicts with that of another control

modem, NMS provides a list of five available network addresses.

Choose one of these addresses and change the address of one of

the modems. Then, return to this section.

After converting the link-level address, NMS issues the Change Protocol Mode (chpm) command

to the control device. This modem then broadcasts the change in mode to its downstream modems

and begins to poll all devices on its poll list using the new protocol. NMS edits the device profiles

for all devices on the tree to reflect the following:

new link-level address

new alternate mode address

new protocol mode

correct system polling status

NOTE

Since the control modem changed its address, all link-level

addresses on the diagnostic tree are updated to reflect this change.

In the conversion of the link-level address from the DATAPHONE II

short-form address to the Advanced mode long-form address, the

alternate mode address in the device profile is used.

NMS provides a list of the original and new link-level addresses for all devices on the affected

tree. NMS identifies any device whose poll list status was changed from active to skipped

(extended control only) in the mode changing process.

When the conversion is complete, refer to the list of original and new link-level addresses provided

by NMS and do the following:

1. Check the status of each device on the diagnostic tree to ensure diagnostic

communications.

2. Determine if devices for which poll list status was changed should be added to their

upstream device’s poll list.

3. Update any user or system routines that have embedded link-level addresses in them. In the

device profile, the Change Protocol Mode (chpm) command automatically converts the

link-level address of the control modem and every device on the diagnostic tree. However,

the command does not change the link-level addresses embedded in routines to reflect the

new addresses. To avoid problems, use mnemonic device names when specifying

individual devices within routines.
