rrr
p = Port number 1 thru 4
cc = Number of Drop Channels, 0-31. 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, 0-31. 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=Unmasked, 1=Masked)
r = reserved (set to value 0)
Example 1:
131123456789ABCDEFGHIJKLMNOPQRSTUV231123456789ABCDEFG
HIJKLMNOPQRSTUV201000000
Port 1’s Drop channels 1–31 using timeslots 1–31. Same for Insert. Port
1’s Line code is AMI. Port 1’s Bipolar Violation is masked.
Example 2:
30412340000000000000000000000000002041234000000000000000000
000000000220000000
Port 3’s Drop channels 1–4 using timeslots 1–4. Same for Insert. Port 3’s
Line code is HDB3. Port 3’s Bipolar Violation is unmasked.
Note: 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.
