Interface Buffer
Size
Buffer size programming is supported in two formats; bits, or milli-seconds. The selected format must be chosen
using the buffer programming command (IBP_). If the buffer is to be programmed in milli-seconds and
plesiochronous slips are required use the receive framing structure command (IRFS_) to define the proper framing
format.
Note: For Drop & Insert: Only milli-seconds format is allowed.

Command:
Response:
Status:
Response:
Where: nnnnnn = 32 to 262144, in 16 bit
increments.
Interface Buffer
Size (Milli-second
Format)
Command:
Response:
Status:
Response:
Where: nn = 0 to 99 (buffer size in milli-
seconds).
Note: For Drop & Insert:
1. nn = 7.5, 15, or 30 (milli-seconds) for
E1CAS format.
2. nn = 6, 12, 24, or 30 (milli-seconds) for
T1S/T1ESFS format.
3. nn = 1, 2, 4, 8, 16, or 32 (milli-seconds)
for all other D&I formats.
