Figure 48: show module configuration t1 sample output with alarm
To troubleshoot a T1 alarm, see the following sections.
Configuration mismatch at opposite ends of the T1 connection
If the configuration at both ends of the T1 line does not match, this produces an alarm. The
most common configuration mismatches include the framing format (ESF or D4/SF) and the
linecoding format (B8ZS or AMI). Make sure these configurations match at both ends. The
most common configuration for framing format is ESF and for linecode is B8ZS (the defaults
for the Secure Router 2330/4134). The Secure Router 2330/4134 Media Gateway supports
only ESF framing on T1 CAS; it does not support D4 framing.
The following figure shows a sample output of verifying the link configuration on the Secure
Router 2330/4134.
