Troubleshooting Physical Layer Alarms on SONET and

Oct 24 2006 · Typically a SONET device sends alarms both upstream and downstream in order to notify other devices of the problem condition Issue the pos report command in order to configure the alarms that the packet over SONET (POS) interface can activate RTR12410−1(config)#interface pos 2/1 RTR12410−1(config−if)#pos report ?

What is a SONET chassis?
A SONET chassis sends alarms in both upstream and downstream directions in order to notify other devices of the problem condition. The interface of an active alarm or defect is maintained in a down/down state. The process used to troubleshoot down/down SONET interfaces is similar to that of digital interfaces, such as T1 and T3.
How does SONET detect events and alarms?
SONET equipment detects events and alarms at each of SONET's three layers -- section, line and path. Typically, a SONET device sends alarms both upstream and downstream in order to notify other devices of the problem condition. Issue the pos report command in order to configure the alarms that the packet over SONET (POS) interface can activate.
How does SONET work in telco space?
SONET is very widely deployed in telco space, and is frequently used in a ring configuration. Devices such as ADMs sit on the ring and behave as LTE-layer devices; these devices strip off individual channels and pass them along to the PTE layer.
What is AIS in SONET?
Typically, a failure condition detected by a SONET device results in one or more error conditions sent both upstream and downstream on the network. An AIS is sent in order to alert downstream devices of a problem and in order to prevent consequential downstream failures or alarms from being raised.
