Provision VT/Port (T1/E1) Interface
INTRODUCTION
This procedure provides step-by-step instructions to provision the VT/Port (T1/E1) interface
for the STS-1 MUX in the MX2820 system.
PREREQUISITE PROCEDURES
Obtain all necessary local instructions before provisioning the VT/Port (T1/E1) interface. The
parameters need to be set to match the desired application.
VT/PORT (T1/E1) PROVISIONING DATA
Provisioning data includes the following:
•Line State
• Line coding
• Line length
• Loopback detection
• Circuit protection
• T1/E1 Line identification
• Excessive Code Violation (XCV) threshold
• VT Hairpin Loopback
• Cross-Connect Mapping
• VT AIS Transmission
T1/E1 Set Multiple
The Set Multiple parameter (value 29) allows setting the same values for a contiguous group
(or all) of the T1/E1 circuits. To set a value for all T1/E1 circuits, set First to 1 and LAST to
28. Select Apply Settings before leaving the menu. To set a value for only some of the T1/E1
circuits, set First and Last to correspond to the lines desired. Select Apply Settings before
leaving the menu.
