NTP-010: Circuit Order 365-575-102
Page2of6 Issue8.0,July2002
Obtain the circuit order instructions to add
OC-3 (LAA10 or LAA10B)/IS-3 (LAA5) circuit
pack(s) and note the assigned address(es).
The address requires a slot assignment.

WARNING:
Traffic on "B" slot could be dropped. Note that restoring the original value of
the OC-3/IS-3 Protection Mode parameter will change 1+1 slot pairs to 0x1
slot pairs. This will, in turn, cause all cross-connections associated with
such a 1+1 slot pair to be associated with the "A" slot only. If such a
transition takes place at the tail end and the "B" slot was the active slot at
that time, an interruption of less than 60 msec will be observed. And, if
such a transition takes place at the head end of a 1+1 protected optical line
while the tail end is active on the "B" slot, the traffic will be dropped with no
alarms being raised.
!
WARNING:
When a pair of slots ("A" and "B" slots) changes from 0x1 to 1+1 operation,
all cross-connections added from those slots will initially select the "A" slot.
This will cause a brief service hit if the original add cross-connection was
from the "B" slot.
NOTE:
OC-3/IS-3 circuit pack provisioning is done on a slot basis.
NOTE:
For Releases 5, 6, and 7.0 only, the alarm level parameter must be
provisioned to NO if the desire is to suppress alarms when there is no
optical input signal present. For releases 7.1 and later, there will be no
alarm with the absence of an optical input signal unless the port has
already been in-service and the input signal subsequently removed.
If required, provision the OC-3/IS-3 slot
parameter(s).
