4-Port High Density FXO-M1 Analog
Voice Interface Card for the Cisco ICS-7750

The Cisco Integrated Communications System (ICS) 7750 brings the benefits of converged IP services to midmarket businesses and enterprise branch offices. The ICS 7750 is a versatile IP telephony and services solution that helps businesses harness the power of the Internet through converged applications enabling them to anticipate and respond to customer needs more efficiently. Call processing, voice applications and multiservice IP routing are integrated within the system chassis to deliver true convergence while enhancing system manageability. The modular system architecture enables expansion of call processing, routing capacity, and IP services to deliver high availability and scalability. The ICS 7750 gives customers the flexibility to choose the optimal configuration for their business environment, and allows them to increase profitability through improved customer interactions.

To keep up with the rapidly changing business environment in the Internet economy, businesses need cost effective yet scalable communication network solutions that plug into traditional voice networks as well as into the Internet. The Cisco Multiservice Route Processor for the ICS 7750 is flexible in that it can provide both connection to voice networks or to the Internet based on the type of interface card required by the customer. When combining the MRP with the high density analog Voice Interface Cards (VICs), the result is cost effective yet scalable analog voice service solution that meets the demanding needs of today's customer.

Product Description: Cisco VIC-4FXO-M1

The high density Cisco VIC-4FXO-M1 Voice Interface Card (VIC) supports up to four Foreign eXchange Office (FXO) M1 analog trunk ports. The VIC-4FXO-M1 is built from industry-proven Cisco hardware and uses industry-proven Cisco IOS® Software technology. Because the Cisco VIC-4FXO-M1 is the same size as the existing two port VICs, it can slide into either one of the two VWIC slots located on the MRP card. Thus, when installing two Cisco VIC-4FXO-M1 cards within a MRP, up to eight FXO-M1 trunk ports can be supported.

DSP Requirements for the VIC-4FXO-M1

Within the ICS 7750 system, the Medium Complexity analog DSP image is the factory default for supporting the VIC-4FXO-M1. This DSP image provides support for four voice channels (of G.711, G.729 or G.726) for each DSP chip. For example, the PVDM-4 has one DSP chip and is therefore capable of supporting 4 voice channels on the VIC-4FXO-M1. The Medium Complexity analog DSP image supports 4 channels of G.711, G.729, G.726, fax relay, modem or fax pass through and provides support for 32 msec Echo Cancellation per DSP chip.

The VIC-4FXO-M1 also supports the High Complexity analog DSP image. This DSP image provides support for two voice channels (of G.711, G.729, G.723.1 or G.726) for each DSP chip. Therefore, a PVDM-8 (two DSP chips) is required to support 4 voice channels on the VIC-4FXO-M1. The High Complexity analog DSP image supports two channels of G.711, G.729, G.726, G.723.1 fax relay, modem or fax pass through and provides support for 32msec Echo Cancellation per DSP chip.
