The Cisco MC3910 series multiservice access concentrator integrates data, voice/fax, and video signals and connects them to Asynchronous Transfer Mode (ATM), Frame Relay, or leased-line networks

Through its various ports, the Cisco MC3910 series concentrator can support a variety of network and user interfaces, including T1/E1 trunks, serial data ports, an Ethernet LAN connection, private branch exchanges (PBXs), telephone key systems, analog telephones, and Integrated Services Digital Network (ISDN) Basic Rate Interface (BRI) services.

Five basic hardware variations of Cisco MC3910 series concentrators are available, based on the choice of optional modules. All five chassis variations are equipped with two serial data ports, one Ethernet 10BaseT port, and two administrative ports.

•Base chassis—No optional modules installed; traffic interfaces are limited to the two serial data ports and one Ethernet port

•Analog voice chassis—Supports up to six analog voice ports; optionally supports T1/E1 trunk, BRI backup, and a video codec dialing interface

•Digital voice chassis—Supports up to 24 channels of toll-quality voice; optionally supports T1/E1 trunk, BRI backup, and video codec dialing interface

•BRI voice chassis—Supports eight channels of voice through 4 BRI ports using QSIG signaling; optionally supports BRI backup and video codec dialing interface

•T1/E1 trunk chassis—Supports a T1 or E1 trunk; optionally supports BRI backup and video codec dialing interface

Cisco MC3910 series concentrators support routing between their various data ports, and they support transparent bridging per Digital Equipment Corporation (DEC) 802.1d and IEEE 802.1d specifications. They can be optionally equipped to support redundancy backup of their wide-area network (WAN) interface ports. Redundancy backup is provided by an optional ISDN BRI port that can be programmed for automatic switchover. This port has an ISDN S/T interface, and this function is referred to here as BRI S/T backup.
