Configuring the STM-1 Mode Ports
and Channels Using the Console
Overview of This Chapter
This chapter describes how to set the values for the port and channel config-
uration for the 1-Port Channelized OC-3/STM-1 CES modules (23N12
(MM)/23N13 (SM)).
Preparatory Steps Before Configuring the Module
Before beginning to configure the 1-Port Channelized OC-3/STM-1 CES
module, be sure you have performed the following steps:
1. Set the values to configure your basic system, see
PacketStar
®
PSAX Multiservice Media Gateway User Guide
for details. Refer to “Related
Reading” on page 1-2 for additional information for the
PacketStar
Multi-
service Media Gateway systems.
2. Set the values to configure the Stratum 3–4 module, see
PacketStar
®
PSAX Multiservice Media Gateway User Guide
for details.
3. If you are using 1+1 protection, make certain that the paired modules are
placed in the correct slots. The left module of the pair must be in an odd-
numbered slot; the right module must be in an adjacent (consecutive)
even-numbered slot. In this placement, either module can serve as the
working or protection module. All PSAX chassis require this placement
scheme for 1+1 protection.
4. If you are not using 1+1 protection, place the module in any I/O slot of
the PSAX 1000, PSAX 1250, PSAX 2300, or PSAX 4500.
Note:
The modules each have a separate set of windows in the console
user interface; however, the procedures for configuring them are
identical. The modules may be configured as a 1+1 protection pair,
or one module may be configured without a second module pro-
viding 1+1 protection. An 1+1 protection pair should always con-
sist of the same module type for module hardware and network
reliability (see “Optical Specifications” on page 2-4 for signal dis-
tance reach). The pair consists of an working module and a redun-
dant protection module. This configuration ensures that if the
working module fails, the protection module takes over.
Figure 4-1 shows a working and protection module setup on the
PacketStar
PSAX 1250 chassis. The modules in protection configuration can be used in
APS/MSP protection configuration in the PSAX 1000, PSAX 2300, and
PSAX 4500 as well.
