I have a requirement to test a system through an ASR 100X to a RS-530 Serial connected modem in loopback.
The key components are:
Anrirsu Tester (DCE) <--------> ASR <----------> Modem(Baseband in loopback)
The ASR is a single device with two connected serial interfaces, one to the tester (S0/1/0) and the other to the modem (S0/1/1), what I essentially need to do is create a transparent bridge between two interfaces on the same device.
This used to be easy on ISR running a standard IOS using 'Bridge Group #' commands, however this command has been deprecated, I have looked into BDI but this would appear to be Ethernet only, there must be some way to achieve this.
The reason for needing this is to test end to end comms on a Satcom site through the router at 8Mbps (RS-530) to carry our BER tests (BERT) over extended serial cable distances up to and including 11 metres.
Any assistance is gratefully received, if any more information is required, please let me know.

I am having the exact same problem utilising TACACS+ / CHAP through ACS 5.2. Using the older version 4.2 it works without issue. During troubleshooting the problem we discovered that if we cahnge the router to use PAP and not CHAP the authentication works fine and passes information via the identity store. Changing it back to CHAP breaks the connection andw e are unable to authorise a user, complains about being in the wrong domain. Still do not have a solution, other than move to PAP which is obviously less secure. It is potentially an issue with CHAP and TACACS not working properly together on ACS 5.2, all documentation discusses RADIUS / CHAP. Look forward to any other information / assistance any has to offer.
