3. Installation and Setup
3.1 Introduction
The T1 and E1 Fiber Muxes, shipped completely assembled, can be installed as desktop units or mounted in
19" racks with the optional Rackmount Kit (RM1001).
This chapter provides mechanical and electrical installation procedures for muxes, including the setting of the
internal jumpers and connecting the mux’s various interfaces.
After installing the mux, please refer to
Chapter 4
for operating instructions and to
Chapter 5
for system-
configuration procedures.
If you encounter a problem, please refer to
Chapter 6
for testing and diagnostics instructions.
WARNING
• No internal settings, adjustment, maintenance, or repairs may be performed by either
the operator or the user; such activities may be performed only by a skilled
technician who is aware of the hazards involved.
• Always observe standard safety precautions during product installation, operation,
and maintenance.
3.2 Site Requirements and Prerequisites
3.2.1 P
OWER
The mux should be installed within 5 feet (1.5 m) of an easily accessible grounded AC outlet capable of
furnishing a supply voltage in the range of 100 to 240 VAC.

ONNECTIONS
On T1 Fiber Muxes
Each T1 Fiber Mux channel interface has one RJ-45 connector. Only one interface can be in use at any time.
The
Appendix
provides the pin allocation for the RJ-45 connector. The maximum allowable line attenuation
between each channel port and the user’s equipment is 2.4 dB.
On E1 Fiber Muxes
Each E1 Fiber Mux channel interface has one RJ-45 connector (for the balanced link interface) and two BNC
connectors (for the unbalanced interface). Only one interface can be in use at any time. The
Appendix
provides the pin allocation for the RJ-45 connector. The maximum allowable line attenuation between each
channel port and the user’s equipment is 6 dB.

ONNECTIONS
Each fiber optic link interface is terminated in two ST connectors. See Table 2-1 for the maximum allowable
attenuation and other fiber optic interface characteristics.
