10BaseT cables
To install a 10BaseT interface, you need a twisted-pair Ethernet cable and a dual
twisted-pair cable terminated with RJ-45 modular jacks.
Use an EIA/TIA 568 or IEEE 802.3 10BaseT cable.
100BaseT cables
To install a 100BaseT interface, you need a twisted-pair Ethernet cable and a dual
twisted-pair cable terminated with RJ-45 modular jacks.
Use one of the following cables: 100BaseT2, 100BaseT4 (not very popular),
100BaseTX, or 100BaseFX.
LPM cable specifications
Depending on the type of DSL service being provided by the associated LIM, LPMs
support two-wire or four-wire connections to the DSL end user.
The LPMs use USOC RJ-21X 50-pin telephone company connectors, as shown in
Figure B-1.

LPM two-wire cable specifications
Depending on the number of ports provided by the associated LIM, an LPM can have
one, two, or three connectors:
■
Table B-3 shows the cable pinouts for the single 50-pin connector for two-wire
connections on an LPM that supports LIMs with 24 ports
■
Table B-4 shows the cable pinouts for the upper 50-pin connector for two-wire
connections on an LPM that supports LIMs with more than 48 ports.
■
Table B-5 shows the cable pinouts for the middle 50-pin connector for two-wire
connections on an LPM that supports LIMs with 72 ports.
