BME Connection Diagnostics

BXM Port LED states

Scenario: For an APS 1+1 or APS 1:1 line pair, the port LEDS are the same color on working and
protection line.
Explanation: To switch software, the APS line pair is a single logical line. Although required to send
BXM messages to both lines, these messages will be the same message. Thus switch software cannot
send different LED states to the BXM for the same APS line. The BXM firmware makes the protection
line LED state the same as the working line LED state.

Troubleshooting VSI Problems

Ths section describes how different types of channels are allocated (VSI, Automatic Routing
Management), and how to troubleshooting some problems related to VSI. Note that some or all of the
commands discussed in this section require service-level or above user privileges. To access these
commands, you must have debug (Service or StrataCom level) privileges and passwords. Check with
the TAC for assistance.

How Channels are Allocated and Deallocated

To understand channel allocation and deallocations problems, it's important to understand how the
channels are distributed. The BXM card can support
different models of BXMs.

How Networking Channels are Allocated

Networking channels are assigned for trunk interfaces only. This includes physical, feeder, and virtual.
Every physical and feeder trunk that is active is assigned 271 networking channels. For virtual trunks,
the first virtual trunk upped on a port is assigned 271 networking channels. Every subsequent one
requires an additional one. So if the second virtual trunk on the same port is upped, one more
networking channel is reserved for that virtual trunk.

How Automatic Routing Management Channels are Allocated/Configured

When a port or trunk interface is upped, a default value of 256 PVC channels are assigned. You can
use the
PVC channels configured. Every time a connection is added on the port or trunk interface, a counter is
