We have 2 MC3810s connected together via a T1 lease line using frame relay encapsulation. Each MC3810 has a DVM connecting a PBX. Both MC3810s are configured with a cross connect between the MFT and the DVM.
We are experiencing voice quality issues, and need QoS. We are unsure of our options. If possible we would like to keep the current config, but if needed it can be redesigned.
Our current config:
controller T1 0
framing esf
clock source internal
linecode b8zs
channel-group 4 timeslots 1-23 speed 64
tdm-group 1 timeslots 24
