Item Description
ISDN Call Reference Length
Set length of the call reference used when a call is placed on an ISDN
interface.
The call reference is equal to the sequence number that the protocol assigns to
each call. It is 1 or 2 bytes in length and can be used cyclically.
When the device receives a call from a remote device, it can automatically
identify the length of the call reference. However, some devices on the
network do not have this capability. In the event that the device is required to
place calls to such a device connected to it, you must configure the device to
use the same call reference length configured on the connected device.
