DCH lamp showing Yellow

[lastation4]

Alright I'm back after a long hiatus on this thing...

I've got everything turned up but I cannot for the life of me get the DCH to establish to my Cisco 2921.

Clock is Green, so that's not it.

EDIT: I get a message on turning on the DCH:

DCH055 DCH: 106 RLS CTS DOWN TIME: 18:50:21 8/06/2025

Unable to get D channel to come up between Meridian and Cisco 2600 series routers.

Change prompt ACRC from yes to no under loop timer
ACRC= auto report on CRC-4 errors

Problems getting D channel and loop to come up between a meridian and a Cisco 2610 router. In this case the Cisco 2610 was expecting to see ACRC set to yes. This was changed to no and the respective change made on the meridian as well. The D channel then came up. (All other parameters as per recommended settings).

Sample configuration as below:
QSIG (ESGF4) to Cisco 2610 series router. (Sample configuration taken from 01302 341000 Business Link, South Yorkshire).

PRI card set to 75 Ohm Coax.
Coax75 ohm to RJ45 125 Ohm converter used to connect to router.

NB, ACRC set to no on the respective loop timer in overlay 73
