where:
p = Port number 1 thru 4
cc = Number of Drop Channels, 0-32. Used to decide Port p’s TX Tributary Rate
if Interface Type is Quad Drop & Insert (ITF=D).
31 bytes of Drop information:
d = 31 bytes defining timeslot locations (or channels)
t = Drop type: (0=reserved, 1=reserved, 2=E1-CCS, 3=reserved)
CC = Number of Insert Channels, 0-32. Used to decide Port p’s RX Tributary
Rate if Interface Type is Quad Drop & Insert (ITF=D).
31 bytes of Insert information:
I = 31 bytes defining timeslot locations (or channels)
T = Insert type: (0=reserved, 1=reserved, 2=E1-CCS, 3=reserved)
Timeslot definition:
0 = Unused
1-9 for timeslots 1–9, A=10, B=11, C=12, D=13…V=31.
L = Line Code: (0=AMI, 1=reserved, 2=HDB3)
M = Bipolar Violation Mask (0=active, 1=masked)
r = reserved (set to value 0)
Example 1:
131123456789ABCDEFGHIJKLMNOPQRSTUV231123456789ABCDEFGHIJK
LMNOPQRSTUV200000000
Port 1’s Drop channels 1–31 using timeslots 1–31. Same for Insert. Port 1’s Line
code is AMI.
Example 2:
304123400000000000000000000000000020412340000000000000000000000
00000220000000
Port 3’s Drop channels 1–4 using timeslots 1–4. Same for Insert. Port 3’s Line
code is HDB3-_.
Notes:
1. This command is a bit forgiving in the sense that the modem accepts the
command even though the interface type is other than Quad Drop &
Insert. This was intentional because it’s being used with the CRS-300
switch for 1:N redundancy.
2. To select Full E1 for the port, set Number of Drop/Insert channel to be 32, and
the timeslot locations to be “123456789ABCDEFGHIJKLMNOPQRSTU”.

Returns current Drop and
Insert configuration of a
single port.
Where n=0 to 9 returns the
