EIA-530 Payload Rate

Possible Settings (Model 8777): 64, 128, 256, 384, 512, 768, 1024, 1536

Default Setting: 1536

Possible Settings (Model 8779): 64, 128, 192, 256, 320, 384, 448, 512, 576, 640, 768, 960, 1024, 1536, 1920, 1984, 2048

Default Setting: 2048

Specifies the synchronous port speed of a remote NTU that is an EIA-530 model so the unit can run at the highest DSL line rate supported.

TEIA-530 Payload Rate is only available when the unit is configured as an LTU.

For the Model 8779 to achieve the payload rates listed above, both the 8779 card and the 7975-A2 endpoint must be operating with firmware 02.03.12 or greater. In lower firmware versions, the payload rate is only selectable at a DSL line rate of 144 Kbps while all other rates default to the maximum, depending on the DSL line rate selected.

64 – 2048 – The synchronous port speed of the remote NTU, in Kbps.

Transmit Attenuation

Possible Settings: 0dB – 15dB

Default Setting: 0dB

Determines how much the unit’s transmit power is reduced to accommodate a short line length.

0dB – The full transmit power is used (no attenuation).

1dB – 15dB – The unit’s transmit power is reduced by the specified amount.

Peer IP Address

(LTU)

Possible Settings: 001.000.000.000 – 223.255.255.255, Clear

Default Setting: 000.000.000.000

SpecifiesTthe peer IP address providing the remote management link on the DSL loop.

Peer IP Address is only available when the unit is configured as an LTU and the unit is in not running in IP Conservative mode.

Address Field (001.000.000.000 – 223.255.255.255) – Enter an address for the peer unit. The range for the first byte is 001 to 223, with the exception of 127. The range for the remaining three bytes is 000 to 255. The IP address must be in the same subnet as the MCC backplane address.

Clear – Clears the IP address and sets to all zeros.
