ISDN BRI0/2/0 interface
 

Hi all, this is my first post here, i want to give you thanks in advance.

Well i have some cisco 2801 with this both lines on isdn status. Any idea of what can it be?

sh isdn status
Global ISDN Switchtype = basic-net3

%Q.931 is backhauled to CCM MANAGER 0x0003 on DSL 4. Layer 3 output may not apply

ISDN BRI0/2/0 interface
dsl 4, interface ISDN Switchtype = basic-net3
L2 Protocol = Q.921 0x0000 L3 Protocol(s) = CCM MANAGER 0x0003
Layer 1 Status:
ACTIVE
Layer 2 Status:
TEI = 0, Ces = 1, SAPI = 0, State = MULTIPLE_FRAME_ESTABLISHED
TEI = 0, Ces = 1, SAPI = 0, State = TEI_ASSIGNED
Layer 3 Status:
0 Active Layer 3 Call(s)
Active dsl 4 CCBs = 0
The Free Channel Mask: 0x80000003

%Q.931 is backhauled to CCM MANAGER 0x0003 on DSL 5. Layer 3 output may not apply

ISDN BRI0/2/1 interface
dsl 5, interface ISDN Switchtype = basic-net3
L2 Protocol = Q.921 0x0000 L3 Protocol(s) = CCM MANAGER 0x0003
Layer 1 Status:
ACTIVE
Layer 2 Status:
TEI = 0, Ces = 1, SAPI = 0, State = MULTIPLE_FRAME_ESTABLISHED
TEI = 0, Ces = 1, SAPI = 0, State = TEI_ASSIGNED
Layer 3 Status:
0 Active Layer 3 Call(s)
Active dsl 5 CCBs = 0
The Free Channel Mask: 0x80000003
Total Allocated ISDN CCBs = 0

We use call manager for voip.

The problem is here:
TEI = 0, Ces = 1, SAPI = 0, State = MULTIPLE_FRAME_ESTABLISHED
TEI = 0, Ces = 1, SAPI = 0, State = TEI_ASSIGNED
On correct status, we have just TEI = 0, Ces = 1, SAPI = 0, State = MULTIPLE_FRAME_ESTABLISHED
