QDI= 73 bytes Command or Query.
Quad Drop & Insert Commands (E1 CCS Only)
QDI=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 Quad Drop & Insert (TFM=8).
d = 32 bytes defining Timeslot locations (or channels)
CC = Number of Insert Channels, 0-32.
Used to decide Port p’s RX Tributary Rate if Interface Type is Quad Drop & Insert (RFM=8).
s = 32 bytes defining Timeslot locations (or channels)
Timeslot definition:
0 = Unused
1-9 for timeslots 1–9,
A=10, B=11, C=12, D=13…V=31
z=timeslot zero
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 (set to value 0)
Example 1:
131123456789ABCDEFGHIJKLMNOPQRSTUV031123456789ABCDEFGHIJKLMNOPQRSTUV00000
Port 1’s Drop channels 1–31 using timeslots 1–31. Same for Insert. E1 clock mode is synchronous (Read-
Write using Port 1 string).
Example 2:
30412340000000000000000000000000000204123400000000000000000000000000002001000
Port 3’s Drop channels 1–4 using timeslots 1–4. Same for Insert. E1 clock mode is asynchronous (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.

Configuration
Save
CST= 1 byte, value
of 0 thru 9
Command only.
Causes the modem to store the current modem configuration in Configuration Memory location in the form
x, where x=0 to 9.
Example: CST=4 (stores the current configuration in location 4)

Load
CLD= 1 byte, value

Command only.
Causes the modem to retrieve a previously stored modem configuration from Configuration Memory location in the
form x, where x=0 to 9
Example: CLD=4 (loads modem configuration from location 4 to be the active configuration)
