CHAPTER 1
Configuring Channelized T3 Interfaces
Use the procedures described in this chapter to configure channelized T3 (CT3) interfaces
on E Series Broadband Services Routers.
This chapter contains the following sections:
•
Overview on page 3
• Platform Considerations on page 5
• References on page 9
•
Before You Configure an Interface on page 9
•
Configuration Tasks on page 10
• Configuration Example on page 22
• Testing Interfaces on page 22
•
Monitoring Interfaces on page 27
Overview
Channelized T3 interfaces are supported by the modules described in this chapter.
Configuration procedures for all channelized T3 physical interfaces are identical; however,
the capabilities of the modules differ. Each port on a CT3 module offers a total
bidirectional rate of 43.008 Mbps.
This section describes the features of channelized T3 interfaces. For information about
configuring channelized T3 interfaces over SONET/SDH, see “Configuring Channelized
OCx/STMx Interfaces” on page 105.
MDL/FDL Support
Channelized T3 interfaces on some line modules support maintenance data link (MDL)
messages at the T3 level and facilities data link (FDL) messages at the T1 level. For a list
of the line modules that support MDL and FDL, see
ERX Module Guide , Appendix A , Module
Protocol Support .
You can use MDL and FDL messages to determine the status of a link and to display
statistics for the remote end of a connection. MDL and FDL messages do not interfere
with other data transmitted over the link.
