Customizing V.35/V.11-Compatible Units
5-4
NOTE:
See Appendix A,
Worksheets
configuration options for your application.
Table 5-1. V.35-Compatible Units Configuration Options
1) SDSL Card Type
Possible Settings: CP, CO
Default Setting: CP
Indicates the placement of the unit in the network configuration. To toggle the card type,
enter 1 at the Config prompt.
CP – Unit is on the customer premises side of the SDSL connection. This automatically
sets the unit to use the SDSL local loop for timing.
CO – Unit is on the central office (or central site) side of the SDSL connection. Timing is
configurable to either internal or external (see option 3).
You must reset the board for this change to take effect. To reset the board, use option R
from the Main Menu. (The board may also be reset by cycling the power on the board.)
2) Payload Rate
Possible Settings: 1 to 32 (64 to 2048 kbps)
Default Setting: 32 (2048 kbps)
Specifies the desired payload rate.
1 – 64 Kbps (1 x 64)
2 – 128 Kbps (2 x 64)
3 – 192 Kbps (3 x 64)
4 – 256 Kbps (4 x 64)
5 – 320 Kbps (5 x 64)
6 – 384 Kbps (6 x 64)
7 – 448 Kbps (7 x 64)
8 – 512 Kbps (8 x 64)
9 – 576 Kbps (9 x 64)
10 – 640 Kbps (10 x 64)
11 – 704 Kbps (11 x 64)
If you change from a full E1 rate (2048 Kbps) to a lower rate, and the far-end unit is
G.703-compatible, you must set the starting time slot on the G.703-compatible unit.
See
Table 4-1
on page 4-4 for more information.
You must reset the board for this change to take effect. To reset the board, use option R
from the Main Menu. (The board may also be reset by cycling the power on the board.)
3) Timing (on CO units only)
Possible Settings: Internal, External
Default Setting: Internal
Determines the timing source. To toggle the timing, enter 3 at the Config prompt. This
option can only be changed on CO units. CP units always use the SDSL local loop for
timing.
Internal – The unit's internal clock is used as the clock source.
External – The V.35/V.11 interface is used as the clock source.
