Channels are defined on the E1 controller. How is that configured? Usually when you see a subset of the total channels configured it's because only a fractional circuit was purchased from the carrier. Be sure to check with them before enabling remaining channels.

Actually, I see 16 channels in pvdm . the issue is when the call come it sends to channel above 16 and it drops.Although 16 channel is not full.
(Requested Channel 18 is not available.)
I configured pri-group timeslots 1-16 command .
can reason be ios?

You have configured it wrong.
You cannot decide on which channel a call comes in,
Either configure for 30 channels, or ask telco to reduce to 15.
