Chapter 1 Getting to Know Your MSC
Management Switch Card User’s Guide

In the central office, your IES should have an Ethernet connection to a backbone network. The IMA
converts ATM cells coming from remote sites to Ethernet frames. Depending on your configuration,
the IMA also converts traffic from double-tagged PVCs to either single-tagged or double-tagged
VLAN frames. The MSC receives the frames and then forwards the frames to the Ethernet network
(backbone).

1.2 Ways to Manage the MSC
Use any of the following methods to manage the MSC.
• Web Configurator. This is GUI-based management using a (supported) web browser. See Chapter
3 on page 63.
• Command Line Interface. Use line commands through Telnet or the console port to manage the
MSC. See Chapter 18 on page 641.
• Editable plain text based configuration file
• FTP for firmware upgrades and configuration backup/restore (Chapter 37 on page 1097).
• SNMP. The device can be monitored by an SNMP manager. See Chapter 14 on page 561 and
Section 34.4 on page 1052.

This section introduces key IES series features.
Management Switch Card Redundancy
You can install two management switch cards to increase system reliability. The two management
switch cards must have the same types of uplink and subtending connections. One management
switch card is active and the other acts as a standby.
