New in Release, MGX 8220 Management

MGX 8220 Management

•Service Resource Module (SRM-T1E1)

This card provides loopback and bit error rate testing (BERT) functions and 1:N redundancy for the service modules.

The ASC and the BNM modules must be present in an MGX 8220 shelf and are referred to as the core modules. The MGX 8220 shelf release 3.0 supports redundant core modules where one ASC/BNM set is an active set and a second ASC/BNM is a standby set. In the event of a malfunction, the standby set automatically takes over as the active set. The SRM is optional. If present, it is part of the core card set, with switchover to the standby upon a malfunction of the active BNM or ASC.

MGX 8220 Management

The functions and operation of the MGX 8220 shelf are achieved through downloaded ﬁrmware. The ﬁrmware controls the overall operation of the shelf and responds to conﬁguration and other commands received from a user terminal or workstation. The MGX 8220 shelf has a command repertoire of over 60 user commands which are used to conﬁgure and display the various operational parameters of the shelf.

The current status and conﬁguration parameters of the MGX 8220 modules are maintained in a Management Information Base (MIB) which is updated by the ﬁrmware as changes in status and conﬁguration occur. The MIB can be interrogated using SNMP commands.

Most of the functions of the MGX 8220 shelf Release 3.0 can be effected through the graphical user interface provided in StrataView Plus 8.2.

The ASC module includes three ports for user input of management commands. A further means of management access is provided in-band over the ATM trunk.

The maintenance port is a simple RS-232 port for direct connection to an alpha-numeric terminal into which the user can type commands through a Command Line Interface (CLI).

The control port (SLIP protocol only), the LAN (Ethernet) port and the In-band ATM connection all support the CLI (via Telnet), TFTP and SNMP protocols for communicating with the MGX 8220 shelf.

New in Release 3.0

This section provides a very brief description of the new MGX 8220 shelf features that have been added since Release 2.x.

•A new Broadband Network Module is available which supports E3 trunking to the BPX switch.

•The new Circuit Emulation Service Modules (CESM) provide support for unstructured synchronous data streams on both T1 and E1 lines.

•The Frame Service Module (FRSM) adds support for frame forwarding on a port-by-port basis.

•The ATM UNI Service Module (AUSM) now supports a number of new features including SRM BERT support, enhanced CAC (Connection Admission Control), and Virtual Path Connection capability.

•The optional SRM (Service Resource Module) which provides for loopback and BERT testing of lines and ports now provides 1:N redundancy for service modules as a feature license.

•The new Inverse Multiplexing for ATM Trunk Module 0- (IMATM) permits BPX nodes to use multiple (up to 8) T1 or E1 lines as ATM trunks instead of a single T3 or E3 line. This card is housed in the MGX 8220 shelf but acts as an extension to the BPX BNI card.
