If you check the status of the PRI does it show as up and with multiple frame established? To me it looks like your serial interface is not in an operational state as it says 0 channels available.

Both pri are down and when I check the serial port it is showing as up.....

Can you please check the status of ISDN with show isdn status?

show isdn status
Global ISDN Switchtype = primary-dms100
ISDN Serial0/1/0:23 interface
dsl 0, interface ISDN Switchtype = primary-dms100
Layer 1 Status:
ACTIVE
Layer 2 Status:
TEI = 0, Ces = 1, SAPI = 0, State = TEI_ASSIGNED
Layer 3 Status:
0 Active Layer 3 Call(s)
Active dsl 0 CCBs = 0
The Free Channel Mask: 0x807FFFFF
Number of L2 Discards = 0, L2 Session ID = 107
Total Allocated ISDN CCBs = 0

The ISDN status is not operational as the state is TEI_ASSIGNED, it should be MULTIPLE_FRAME_ESTABLISHED. That’s why the trunk shows as non functional. You’d need to check why the ISDN state is not in an operational mode. You can start by checking that the light indicator on the port shows as on another port that is operational and you can check the output from debug isdn q921.

Ok thanks. I ran the isdn debug command but how do you view the results?

To see the output in the terminal you need to enter the command terminal monitor and you cannot have no logging terminal in configuration.



Response Signature


 The Layer 1 Status is  ACTIVE, The ISDN is not UP probably  due to framing which is configured.
