T1 DTE
Connection
The unit is supplied with a T1 DTE jack, that functions only if the unit is equipped
with the T1 DTE interface application module (in Slot 1). This function provides a
DSX1-level interface which allows the user to pass DS0 channels through the unit
from the network side to other T1-oriented equipment via the T1 DTE port.
A typical installation divides the channel usage so that DS0 channels carrying
high-speed data are mapped to the high-speed data ports while all other channels
are passed through to meet other application requirements.
The DTE DSX1 line build out level should be set as shown in DSX Level in DSX
Level on page 27. The T1 DTE physical interface is a standard RJ- 48C connector
with the following pinout.
Network
Connection The network side of the unit is referred to as the network interface. This interface
contains an ALBO (automatic line build out) that allows the unit to be located a
substantial distance away from the telco network interface with a receive signal
level to
−
27 decibels.
