E&M/TO

STATUS

DESCRIPTION

The E&M/TO is a channel unit that provides an interface between a Total Access

750/850/1500 channel bank PCM interface and a VF transmission facility with E&M

DC signaling supervision. The E&M/TO features:

■

E&M or TO Mode

■

Dial pulse distortion correction option

■

Digital loopback to the network,

■

Compatible with types I, II, III, or V E&M signaling interfaces

■

2-wire or 4-wire mode

Note: Use in a Total Access 850 requires a BCU.

TURNUP STEPS

Unpack the Total Access 750/850/1500 E&M/TO card and inspect for damage. If

damage is apparent, refer to your carrier or supplier for replacement.

Verify SW2, SW3, and SW4 are provisioned properly for your application. Refer to

the table in this job aid for default provisioning and other provisioning options.

Insert E&M/TO card into a Total Access 1500 chassis slot 1-24, or Total Access 750

Chassis slots 1-6. To insert, hold the card by the front panel while supporting the

bottom edge of the card. Align the card edge with the guide groove in the Total

Access 750/850/1500 chassis. Insert into chassis until the edge card connector

seats firmly into the chassis backplane. Lock the unit in place by pushing in on

the locking lever. The unit will automatically map DS0s in the T1 determined by

the LIU operational configuration. Automatic assignment can be overridden by

manually changing the T1 mapping in the LIU menuing system.

Verify LED sequencing. LEDs will stop sequencing once unit is initialized.

Provisioning – The Total Access 750/850/1500 supports two types of provisioning modes, local and

remote. Local provisioning results in the unit operating as defined by the onboard switches.

Remote provisioning, if chosen, results in the unit operating as defined by the system controller

menu settings (onboard switches are ignored). The operational mode is indicated by the REM LED

and can be changed by activating the Alternate Provisioning (AP) front panel switch.

Connect VT100 compatible terminal to BCU/SCU front panel ADMIN port.

6a. Connect DB-9 cable

6b. Run terminal emulation program

6c. If using Windows HyperTerminal, open by selecting Programs/Accessories/Hyperterminal

6d. Login and navigate through the ADMIN port menu structure

Note: To ensure proper display background, select VT100 Terminal Emulation under settings.

Navigate through menus to perform desired function.

Note: To traverse through the menus, select the desired entry and press Enter. To work backward in the

menu, press ESC (escape key).

TESTING

Initiated Test

■

Digital Loopback Test – loop back DS0 data coming from the network for each individual channel.

■

1004 Hz DRS Tone Generation Test – sends DRS signal to loop, network, or both.

Note: All tests initiated through the Total Access 1500 SCU/Total Access 750 BCU admin port.
