Drop and Insert Commands
These commands effect the operation of the T1/E1 Drop and Insert NIM.
drop-and-insert-group
This command, which takes no parameters, instructs the T1 controller to offer all its idle time slots
not configured as part of a channel‐group to the Drop and Insert (D&I) agent. The T1 controller thus
operates in mixed Data/Voice mode.
For T1 lines, robbed bit signaling is used for Channel‐Associated Signaling (CAS). Robbed Bit
Signaling uses one bit of each timeslot for signaling every sixth frame. The XSR is configured in
such a way that RBS is disabled for data timeslots (timeslots belonging to a channel group) and
data can be passed at 64 or 56 Kbs.
When the command is issued for both T1 controllers on the NIM, time slots which are idle on both
ports will be connected.
It is mandatory that the T1 port connected to the Central Office derive its timing from the up
stream line and the port connected to the PBX supply timing to the downstream line.

Syntax of the "no" Form
The no form of this command removes Drop and Insert functionality:

PSES is a second with 44 or more PCVs, one or more Out‐of‐Frame defects, or
a detected incoming AIS. This gauge is not incremented when unavailable
seconds are counted.
of‐Frame defects, or a detected incoming AIS. This gauge is not incremented
when unavailable seconds are counted.
SEFS is a second with one or more Out‐of‐Frame defects or a detected
incoming AIS.
UAS are calculated by counting the period the interface is unavailable.
LES is a second with one or more code violations or one or more LOS defects.
CES is a second with one or more C‐bit code violations (CCV), one or more
Out‐of‐Frame defects, or a detected incoming AIS. This gauge is not
incremented when UASs are counted.
CSES is a second with 44 or more CCVs, one or more Out‐of‐Frame defects, or
a detected incoming AIS. This gauge is not incremented when UASs are
counted.
For use if the device downstream is a PBX using rob bit signalling. Entering no
parameter is equivalent to entering the no command.
For use if the device downstream handles data such as a Voice over IP.
