Hi everyone,
I desperately need your help! I am trying to enable dialup internet access termination on AS5400 using SS7 connection to telco switch via PGW v9.6.1. and integrated SLT. I am having trouble configuring the RLM control link between PGW and AS5400. PGW does not sent any rlm packets to as5400.
Here is the AS5400 config:
!
controller E1 6/0
framing NO-CRC4
channel-group 15 timeslots 16
pri-group timeslots 1-15,17-31 nfas_d primary nfas_int 0 nfas_group 0 rlm-group 0
!
interface Serial6/0:15
no ip address
encapsulation ss7
channel-id 0
!
interface Dchannel6/0
no ip address
encapsulation ppp
dialer rotary-group 0
dialer-group 1
no snmp trap link-status
isdn incoming-voice modem
!
rlm group 0
protocol rlm port 3001
server pgw
link address 10.10.2.10 source Loopback0 weight 1
!

ss7 session 0 address 10.10.2.10 8061 10.10.1.220 8061 session-set 0
!
Here is PGW config

The problem is that IP link to as5400 is not coming in-service and as a result the associated naspath control link is not coming up.

The strange thing is that I can't set IP Link IN-SERVICE:

pgw mml> set-iplnk:iplnk-2:IS

/* Route to AS5400 */
;
pgw mml>
The packet trace shows that PGW is NOT sending any rlm packets to AS5400.
PLEASE HELP!
