1.5 INSTALLATION

The following section provides information for installing an 86445-31 FXS unit.
The unit is shipped from the factory configured as per the Node Assignment
Drawing for the purchased system. All spare units or loose units are shipped
with factory default settings in memory.
The 86445-31 2W FXS unit has ESDS components and therefore standard
static protection precautions should be observed when handling, packing

Pre-installation

Visually check the unit for damage. Ensure that screws are firmly tightened and
in place. Keep the shipping containers and packing materials for future use. If a
unit is damaged, file a claim with the shipping agent or the local GE Multilin
representative.
Set the unit line impedance, network build-out capacitance (NBOC), and current
limiting as desired. Refer to the strapping options in Table 1. Factory default
settings are 600Ω for line impedance, 0nF for NBOC, and 20mA for current
limiting.
