Using the Console Interface
This chapter describes how to set the values for the port and channel
configuration for the 1-Port Channelized STS-1e, T1 Format module using
the PSAX Multiservice Media Gateway system console interface.
Be sure to complete the following actions first before configuring the 1-Port
Channelized STS-1e, T1 Format module:
•
Configure your basic system (see "Configuring the System for Your Site"
in Chapter 4 of the appropriate PacketStar
Gateway user guide)
•
Configure the Stratum 3–4 module (see "Configuring the Stratum 3–4
Module" in Chapter 4 of the appropriate PacketStar
Media Gateway user guide)
When configuring the 1-Port Channelized STS-1e, T1 Format module using
the PSAX Multiservice Media Gateway console, display-only fields are
displayed with brackets.
The status line at the bottom of the console window gives instructions for the
field currently selected, and displays trap messages (see the appendix of your
chassis user guide for a table of defined trap messages).
To aid network troubleshooting and testing, loopback capability is provided
for the 1-Port Channelized STS-1e, T1 Format module. The loopback option
on the module's port and channel configuration window for the module
enables you to verify the integrity of a port by transmitting a received signal
back to the source. Selecting a loopback option is described in the module
configuration procedure provided in this chapter.
If configuring a pair of 1-Port Channelized STS-1e, T1 Format module in the
primary and standby setup, the desired loopback option must be configured
by the user on both the primary and standby modules prior to bringing the
pair into service. This parameter is applied on a port-by-port basis on both
the primary and standby modules. If the line loop or local loop configuration
is transferred from port A on the primary module to port B on the standby
module, the port parameter does not transfer; it must be pre-configured on
the standby by the user.
Figure 3-1 illustrates the line loop, payload loop, and local loop options.
