Parameter Setting Description

Framing ESF or D4 DefaultÑESF. Select the Network T1 framing format.

Line Code B8ZS or AMI DefaultÑB8ZS. Select the Network T1 line code

format.

LBO 0dB, -7.5dB, or

-15dB

DefaultÑ0dB. Select the Line Build Out value used

for tuning the attenuation between the DSU/CSU and

the last repeater on the T1 circuit. For instructions, see

Factory Default ConÞguration on page A-13.

Interface Read-only DefaultÑDACS. In the new 3.2 Þrmware version,

NET Interface is DACS read-only and does not appear

in Menu-4 when both

DSU/CSUs are running the

new Þrmware version. The DSU/CSU uses the

Main/Alt Sync timing source (temporarily switching

to NETWORK timing only when in network

loopback). The NET Interface appears in Menu-4 only

when one of the

DSU/CSUs is a Multi-port

DSU/CSU or a Solo Encore/ SoloT1 running an older

version containing NET Interface. On this

DSU/CSU, you can conÞgure NET Interface for

DACS or Non DACS. In the new 3.2 Þrmware

version, NET Interface appears blank on the screen

when on the local

DSU/CSU and DACS read-only

when on the remote

DSU/CSU.

DACS

Select DACS if the DSU/CSU is connected to a

Digital Access Cross Connect System that provides

timing to all connected circuits. The speciÞed clock

selection is used even during tests. If it, or its

alternate, is not available, the

DSU/CSU uses

NETWORK timing. If your application is fractional,

set all connected

DSU/CSUs to NETWORK timing.
