Hello,
I wonder if someone has a working ISDN2 (basic-net3) config they can share for point to multipoint (ideally in the UK).
I have always had ISDN2 circuits presented as point to point with a single BRI circuit (2 channels, one physical presentation) delivered on a single NTE and this config has always worked for me with static-tei assigned and isdn point-to-point.
However I have a new site going live and can't get the ISDN2 layer 2 to stay up consistently. The new circuit is presented as a MSN (multiple subscriber number) where there are two circuits (4 channels, two physical presentations) delivered on one NTE. I have worked with TAC but we still cant get the Layer 2 to stay up. Sometimes I get MULTIPLE FRAME ESTABLISHED on both circuits only for a call to come in and no audio be heard and we tear the call down with a temp failure.
The only way I can currently get a stable environment is by shutting down one of the BRI's and when we only have a single BRI activated we can get call in and out with no problem. I just need to bring the second BRI up.
This is the config that is on there at the moment :-
!
interface BRI0/1/0
no ip address
no ip redirects
no ip unreachables
no ip proxy-arp
shutdown
isdn switch-type basic-net3
isdn incoming-voice voice
isdn bind-l3 ccm-manager service mgcp
isdn sending-complete
!
interface BRI0/1/1
no ip address
no ip redirects
no ip unreachables
no ip proxy-arp
isdn switch-type basic-net3
isdn incoming-voice voice
isdn bind-l3 ccm-manager service mgcp
isdn sending-complete
!
When I do a no shut on int BRI0/1/0, and put in a test call I get this TEMP FAILURE :-

Then the BRI circuits drop layer 2 and I need to shut Int BRI 0/1/0 to get Int BRI 0/1/1 back up :-
ISDN BRI0/1/0 interface
dsl 2, interface ISDN Switchtype = basic-net3
L2 Protocol = Q.921 0x0000 L3 Protocol(s) = CCM MANAGER 0x0003
Layer 1 Status:
ACTIVE
Layer 2 Status:
TEI = 255, Ces = 1, SAPI = 0, State = ESTABLISH_AWAITING_TEI
Layer 3 Status:
0 Active Layer 3 Call(s)
Active dsl 2 CCBs = 0
The Free Channel Mask: 0x80000003
%Q.931 is backhauled to CCM MANAGER 0x0003 on DSL 3. Layer 3 output may not apply
ISDN BRI0/1/1 interface
dsl 3, interface ISDN Switchtype = basic-net3
L2 Protocol = Q.921 0x0000 L3 Protocol(s) = CCM MANAGER 0x0003
Layer 1 Status:
ACTIVE
Layer 2 Status:
TEI = 255, Ces = 1, SAPI = 0, State = ESTABLISH_AWAITING_TEI
Layer 3 Status:
0 Active Layer 3 Call(s)
Active dsl 3 CCBs = 0
The Free Channel Mask: 0x80000003
Total Allocated ISDN CCBs = 0
Any assistance would be greatly appreciated.
Many thanks
