Programming the Number of Channels (No. Channels)

Number of channels given by the E1 PRI provider should be programmed to the system so it knows how many
channels the system should have equipped. E1 PRI can handle a total of 30 channels (30B+2D channels).
Your E1 PRI Supplier can supply you with a fractional E1 or a full E1.
30Channels are programmed as default.

CRC-4 (Cyclic Redundancy Check 4) is a form of cyclic redundancy checking (a method of checking for errors
in transmitted data) that is used on E-1 trunk lines. This check has to be turned on or off depending on your E1
PRI supplier.
