craft port by selecting 

Configuration

, 

Network Interface

 and 

Timing 

from the 

Main Menu

, or by ensuring 

continuity to and proper provisioning of the MX2800 and connecting equipment.

At the DS1 level, the MX2800 has three Service States. They operate as follows:

• Disabled – No signal continuity exists through the MX2800, and no alarms are detected or transmitted.

• Enabled – Signal continuity and alarming are always enabled.

• Auto Enable (default) – Signal continuity and alarming exist only after a DS1 signal is detected at the 

DS1 input to the MX2800. Once a signal is detected, the only way to disable alarming is to momentarily 
toggle the DS1 channel to the Disable state as follows:

From the Main Menu, select 

Configuration

, 

T1/E1 Interface 

and 

T1 State

. From the 

T1/E1 State

 screen, 

enter the DS1# in question; then disable signal continuity and alarm transmission. Repeat the process of 
selecting the DS1 from the T1/E1 State screen, but this time select 

Auto Enable

 to once again provision the 

slot/channel for service. No alarms are transmitted until a DS1 signal has been detected and removed, or an 
unframed signal is detected.

After the previous tests are successfully completed and the default settings are restored, the MX2800 can 
be considered ready for customer traffic. Specific provisioning of the DS3, DS1, and other options is deter-
mined by circuit orders and local practices.
