Cisco 2199 PX Router Issue

[quaium]

Just wondering if someone could help with an issue we're having at the moment. We are suddenly not able to receive internal calls or make any external calls. We have contacted our line providers and they have said that everything looks good with the line and are blaming an internal fault with the system.

 

I have done some testing, running the "show ISDN status" command shows the following:

 

 

pxrouter>show isdn status

Global ISDN Switchtype = primary-net5

 

%Q.931 is backhauled to CCM MANAGER 0x0003 on DSL 0. Layer 3 output may not apply

 

ISDN Serial0/0/0:15 interface

dsl 0, interface ISDN Switchtype = primary-net5

L2 Protocol = Q.921 0x0000 L3 Protocol(s) = CCM MANAGER 0x0003

Layer 1 Status:

DEACTIVATED

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: 0x00000000

Number of L2 Discards = 0, L2 Session ID = 204

Total Allocated ISDN CCBs = 0

 

 

Layer 1 Status is showing as deactivated. On the router itself, the "AL" light is showing amber. The strange thing is with the cable unplugged the "AL" light on the router is still showing as amber and if I run the "show ISDN status" command, it's still showing "Layer 1 Status: DEACTIVATED"

 

I also ran the "show inventory" command and the interface card is shown with details of serial number so I think the card is not at fault.

 

Attached are some pictures of the PX Router and the BT box, could anyone help out and let me know how we can resolve this and if it is in fact in internal issue or an external one with our line providers?
