Response to Query
Quad Drop &

QDI=
73 bytes
Command or Query.
Sets or returns Quad Drop & Insert (QDI) (E1-CCS only) in the form
pccddddddddddddddddddddddddddddddddCCssssssssssssssssssssssssssssssssmrrr, 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 QDI (TFM=8).
dddddddddddddddddddddddddddddddd=32 channels (bytes) defining Timeslot locations
CC=Number of Insert Channels, 0-32. Used to decide Port p’s RX Tributary Rate if Interface Type is QDI (RFM=8).
ssssssssssssssssssssssssssssssss=32 channels (bytes) defining Timeslot locations
Typical for Drop or Insert Timeslot definition:
0=Unused
z=Timeslot 0 (zero)
1-9=Timeslots 1 through 9
A=Timeslot 10 through V=Timeslot 31
m=E1 Clock Sync/Async mode (Read/Write on Port 1 string, Read-Only on other Ports strings). This is NOT a per
port setting, but a global setting. 0=E1's are asynchronous, 1=E1's are synchronous.
r=Reserved (value fixed at 0)
EXAMPLE 1:
QDI=131123456789ABCDEFGHIJKLMNOPQRSTUV031123456789ABCDEFGHIJKLMNOPQRSTUV00000
(Port 1’s Drop and Insert channels 1-31 each using timeslots 1-31. E1 clock mode is asynchronous (Read-Write using
Port 1 string).)
EXAMPLE 2:
QDI=3041234000000000000000000000000000004123400000000000000000000000000001000
(Port 3’s Drop and Insert channels 1-4 each using timeslots 1-4. E1 clock mode is synchronous (Read-only parameter in
Port 3 string).)
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 is intentional for use with the CRS-300 switch for 1:N redundancy.

Command only.
Stores the current modem configuration in Configuration Memory location in the form x, where:
