Stinger OC12-ATM Trunk Module Guide 1
Configuring the OC12-ATM
Trunk Module
The OC12-ATM trunk module provides dual 622Mbps synchronous optical network
(SONET) synchronous transport signal 12 concatenated (STS-12c) or synchronous
digital hierarchy (SDH) synchronous transport module level 4 (STM-4) ports. These
fiber optic interfaces can be configured to share bandwidth in a cascade arrangement
that links multiple Stinger FS or FS+ units together to share a single unprotected link
from one of the Stinger units to an ATM core network. If a Stinger unit is equipped
with optional automatic protection switching (APS) capability, the interfaces can be
configured as one active port and one standby port to provide a 1+1 APS connection
to the ATM switch.
A Stinger FS or FS+ chassis fully supports a maximum of one OC12 trunk module per
chassis. This OC12 trunk module can be used in combination with an OC3, DS3, or
E3 trunk module in the other trunk module slot, and with TRAM cards in the unit.
Two versions of the OC12-ATM trunk module are supported:
■ OC12-ATM—single mode, intermediate reach
■ OC12-ATM—single mode, long reach

2 Stinger OC12-ATM Trunk Module Guide
Configuring the OC12-ATM Trunk Module
Introducing the OC12-ATM trunk module
Both OC12-ATM trunk modules are installed and configured in the same way.
Note The OC12 trunk module is supported only on Stinger FS or Stinger FS+ units
equipped with version 2, or later, control modules.
Introducing the OC12-ATM trunk module
Stinger FS and FS+ units can fully support a maximum of one OC12 trunk module,
which is available in the following versions.
Note The reach of the interface can be verified by checking the reach-type
parameter in the transceiver-info subprofile of the trunk-daughter-dev profile, see
“Checking daughter card status” on page 22.
Installing an OC12-ATM trunk module
See the Stinger Getting Started Guide for installation instructions. A Stinger FS or FS+
chassis fully supports the installation of one OC12 trunk module per chassis.
After installing the OC12-ATM trunk module and connecting it to a link to an ATM
switch, you verify connection by checking the status lights. You then configure the
physical link. Use a status profile to display the state of the OC12 line and any error
conditions.
OC12-ATM trunk module specifications
The OC12-ATM trunk module provides two 622-Mbps ports for optical connections.
Each port supports the STS-12c and the STM-4 interface standards. Communication
between an active OC12-ATM trunk module port and the active Stinger control
module takes place directly over the Stinger back plane.
You can configure each port as one of the following:
■ User-to-Network Interface (UNI)
■ Private Network to Network Interface (PNNI) connection
■ Direct trunk
Product code Description
STGR-TM-OC12 Two-port trunk module with OC12/STM-4 interface (single
mode, intermediate reach) for operation at 622Mbps per
port over single-mode fiber, at distances up to 15km (9.3
miles).
STGR-TM-OC12-L Two-port trunk module with OC12/STM-4 interface (single
mode, long reach) for operation at 622Mbps per port over
single-mode fiber, at distances up to 40km (24.9 miles).

6 Stinger OC12-ATM Trunk Module Guide
Configuring the OC12-ATM Trunk Module
Configuring an OC12-ATM trunk module
Configuring an OC12-ATM trunk module
An OC12-ATM trunk module supports two 622Mbps interfaces. Its ports can be
configured to share bandwidth in a cascade arrangement, linking multiple Stinger FS
or FS+ units together to connect to an ATM core network over a single unprotected
link. The ports can also connect to an ATM switch with 1+1 automatic protection
switching (APS), when the APS option is installed on the unit.
The Stinger unit creates a SONET profile for each OC12 interface detected in the
system. The sonet profiles provide an interface to the physical ATM framer associated
with each interface, which supports the standard Universal Test and Operations
Interface for ATM, Level 2 (UTOPIA Level 2).
Overview of SONET settings
The following parameters in the sonet profile are for configuring an OC12-ATM
SONET interface. The parameters are shown with default settings for the first port of a
trunk module in slot 17.
[in SONET/{ shelf-1 trunk-module-1 1 }]
name = 1:17:1
physical-address* = { shelf-1 trunk-module-1 1 }
enabled = no
ignore-lineup = system-defined
aps-config-name =
line-config = { 0 851 payload-atm no-loopback sonet no no vpi-0-255-vci-32-8191+
atm-config = { ast-x43 ast-x43 yes }
spare-physical-address = { any-shelf any-slot 0 }
sparing-mode = inactive
Parameter Specifies
name
Identifies the name of the interface. Currently, only the
default value is supported. This consists of the physical
address of the port in the form, shelf:slot:item (for example,
1:17:1).
physical-address
A read-only field that identifies the physical address of the
trunk port in the Stinger unit in the form, {shelf-#
trunk-module-# item} (for example, {shelf-1
trunk-module-1 1}.
enabled Enables or disables the OC12-ATM interface. Valid entries
are:
■ yes—the interface is enabled
■ no (default)—the interface is disabled
ignore-lineup Allows the line status of the port to be ignored when
attempting to establish connections configured on the port.
Valid entries are:
■ yes—ignore the status of the port
■ no—only attempt to establish configured connections
on the port if the line is up
■ system-defined (default)—use the ignore-lineup
setting in the system profile
