MCC Card

3.1Introduction

This chapter provides installation, configuration, and troubleshooting information for the Management Channel Concentrator (MCC) card.

Note that this card is labeled as an ACS card on its faceplate ejector, and it is called an ACS-MCC card only in the user interface screens described in this chapter. Throughout this chapter, it is referred to as the ACS-MCC card.

3.2.1ACS-MCC Card Description (881360)

The ACS-MCC card uses 631xx MCC firmware and allows you to manage remote Integrated Access Systems by using TCP/IP or SNMP/UDP/IP communication protocols. The control link to each remote system can be the FDL (Facility Data Link) bits of an ESF-framed T1 line. Or, for an E1 line, this link can use the SA4 bits in the frame alignment words of the E1 signal. Full time slot B7R requires a DACSII 6.1 or equivalent. MCC doesn’t talk direct to FDL link, this requires a DACs to convert full timeslot B7R to B4R.

The ACS-MCC card incorporates four Munich32 chips (two on the main board and two on a daughterboard). which allow up to 128 WAN interfaces. The ACS-MCC card also supports three configurable high-speed ports (C1, C2, and C3), plus an Ethernet 10Base-T port for LAN routing management.

The MCC can route IP datagrams between all of its interfaces, based on each datagrams IP destination address. Datagrams are directed (or routed) to the interface carrying the sub-net to which the datagram belongs or is being transported to, according to the content of the routing table. The routing table may be supplied with dynamic routes from the Routing Information Protocol (RIP) when enabled. If no match is found in the routing table, a default route can be designated to direct all unresolved datagrams to a specific interface.

Figure 3-1shows the role of the ACS-MCC card in a Network Management System. Both SNMP alarm traps and TELNET configurations run over this path. They can use the FDL (T1 line), the SA4 bit of the frame alignment word (E1 line), or a full DS0 time slot of a T1 or E1 line.
