T1 NET
Configuration
The T1 NET Configuration screen (Figure 3-8) allows setting the following
network configuration parameters.
Defaults are shown underlined.
Framing Type
Selects the framing for the T1 network. The choices are D4 and ESF.
Line Code
Sets the network side line coding. The choices are AMI and B8ZS.
Line Build Out
Sets the line build out for the network interface. The choices are 0 dB, -7.5 dB,
-15 dB, and -22.5 dB.
Timing
Sets the timing source to synchronize the unit’s internal timing generators. In all
cases, slips are controlled to occur on frame boundaries at the network and /or
DSX1 ports when timing synchronization is lost. The choices are as follows.
INTERNAL
The unit’s internal frequency standard is used for all timing.
NETWORK
Timing is derived from the network-recovered clock (the most common selection
for most applications).
STATION
Timing is derived from a bipolar- or TTL-compatible clock supplied to the unit
through the rear panel. This field shows the input timing and only appears when
