Two things are essential:
1. The LB532A-L model works with the LB532A-R model. Every local line port must
connect to a remote line port.

2. To function properly, the LB532A needs one twisted pair of metallic wire. This
twisted pair must be unconditioned, dry, metallic wire, between 19 (0.9mm) and
26 AWG (0.4mm) (the higher number gauges will limit distance). Standard dial-
up telephone circuits, or leased circuits that run through signal equalization
equipment, or standard, flat modular telephone type cable, are not acceptable.
The RJ-45 line connector on the LB532A’s twisted pair interface is polarity insensitive
and is wired for a two-wire interface.
3.2 CONNECTING THE ETHERNET INTERFACE
This section describes how to connect the Ethernet ports to your network equipment.
The RJ-45 ports labeled Ethernet are the Auto-MDIX 10/100Base-T interface. These
ports are designed to connect directly to a 10/100Base-T device or network. You may
connect these ports to a hub or PC using a straight through or crossover cable that is
up to 328 ft long.
The interconnecting cables shall be acceptable
for external use and shall be rated for the
proper application with respect to voltage, cur-
rent, anticipated temperature, flammability, and
mechanical serviceability.
