MCC Card
22.1 Introduction
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.
22.2 ACS-MCC Card Descriptions
22.2.1 ACS-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 S
A4
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 22-1 shows 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 S
A4
bit of the frame alignment word (E1 line), or a full DS0 time slot of a T1 or E1
line.
