2-12 I NSTALLATION
T1 DTE Port
Connection The 3001 provides an optional T1 DTE port interface for drop and insert applications.
The DSX-output level should be set as instructed in T1 DTE LBO on page 2-8.
The DTE physical interface for both the stand -alone unit and the chassis mounted
unit is a standard RJ-48C 8- pin modular jack with the pinout shown in Table 2-11.
Network
Connection The network side of the 3001 is referred to as the network interface. This interface
contains an ALBO to allow the unit to be located a substantial distance away from
the telco network interface (receive level to -27 dB).
The network interface line build out levels should be adjusted as instructed in
Network LBO on page 2 -4. The maximum suggested cable lengths for unit
connection to the network are listed below. Calculations are based on a cable
temperature of 70°F, 0.083-
µ
F/mile capacitance, a 27-dB loss, and a 100-
Ω
,
non-loaded, twisted pair cable. PIC refers to plastic insulated cable.
The network physical interface for both the stand-alone unit and the chassis
mounted unit is a standard RJ-48C 8- pin modular jack with the pinout shown in
Table 2-13.
