Appendix F Command Set Description
Commands
F-43
The display fields are as follows:
•
FRAME LENGTH
- Total number of bits contained in one main link frame, and
the main link data rate, in kbps.
•
BIT WEIGHT
- Main link bandwidth allocation unit, in kbps.
•
DATA USAGE
- The main link bandwidth allocated to user data, in kbps.
•
CONTROL USAGE
- The main link bandwidth allocated to the transfer of user
end-to-end signaling in kbps.
•
SYNC USAGE
- The main link bandwidth allocated to the frame
synchronization word, in kbps.
•
DOWNLOAD USAGE
- The main link bandwidth allocated to the
management channel, in kbps.
•
TOTAL USAGE
- The total main link bandwidth currently allocated, in kbps.
•
TOTAL FREE
- The total main link bandwidth, in kbps, that is not yet allocated
and is free.
Display Format - MANUAL Frame Bit Allocation
A typical DSP ST FRAME display when the frame bit allocation mode (selected by
means of the
DEF SYS
command) is manual is shown below:
FRAME LENGTH = 160 BIT (128.0 KBPS)
BIT WEIGHT = 0.800 KBPS
BYPASS_START = 16 BYPASS_SIZE = 20
I/O CH1_START CH1_SIZE CH2_START CH2_SIZE CNTRL_START CNTRL_SIZE LAST_BIT

The display shows the number of bits in the frame, and the bit “weight” (main link
bandwidth allocation unit), followed by the bypass information and bandwidth
utilization of each slot:
•
BYPASS_START
- The number of the first bit in the block of bits being
bypassed.
•
BYPASS_SIZE
- The total number of bits being bypassed.
•
CH_START
- The number of the first bit in the block of bits assigned to the
channel of the module installed in the corresponding slot.
•
CH_SIZE
- The total number of bits assigned to the channel of the module
installed in the corresponding slot.
•
CNTRL_START
- When end-to-end transmission of control signals is used,
shows the number of the first bit in the block of bits assigned to carry the
control signals of the module installed in the corresponding slot.
•
CNTRL_SIZE
- When end-to-end transmission of control signals is used, shows
the total number of bits assigned to carry the control signals of the module
installed in the corresponding slot.
•
LAST_BIT
- The number of the last bit in the block of bits assigned to the
module installed in the corresponding slot.
