EIA-530 Payload Rate
Possible Settings (Model 7974): 64, 128, 256, 384, 512, 768, 1024, 1536
Default Setting: [Highest multiple of 64 Kbps supported by the DSL Line Rate]
Possible Settings (Model 7976): 64, 128, 192, 256, 320, 384, 448, 512, 576, 640, 768,
960, 1024, 1536, 1920, 1984, 2048
Default Setting: [Highest multiple of 64 Kbps supported by the DSL Line Rate]
When the NTU has an EIA-530-A interface, the Payload Rate set on the LTU determines
the port speed of the synchronous port of the NTU. See
DSL Line Rates for DSX-1, and
for information about maximum payload rates for different DSL line rates.
T
Payload Rate is only available when the unit is configured as an LTU.
T
To achieve the payload rates listed above, the Model 7975-A2 endpoint must be
operating with firmware V02.03.12 or greater and the Model 7976-A2 endpoint must
be operating with firmware N02.03.12 or greater. In lower firmware versions
(N.02.03.05 and below), 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 Payload Rate, 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 unit's full transmit power is used (no attenuation).
1dB – 15dB – The unit's transmit power is reduced by the specified amount.
Peer IP Address
Possible Settings: 001.000.000.000 – 223.255.255.255, Clear
Default Setting: 000.000.000.000
Specifies the peer IP address for the NTU, to provide remote management providing the
remote management link on the DSL loop.
T
Peer IP Address is only available when the unit is configured as an LTU, and is 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.
Clear – Clears the IP address field and sets to all zeros.
Circuit Identifier
Possible Settings: ASCII text field , Clear
Default Setting: [blank]
Uniquely identifies the circuit number of the transmission vendor's DSL line for
troubleshooting purposes.
ASCII text field – Enter a maximum of 128 characters. All printable ASCII characters
except the ^ (caret) are allowed.
Clear – Clears the field.
