Cisco VIC-4FXS/DID Analog Voice Interface Card
for the Cisco ICS 7750
The Cisco ICS 7750 Integrated Communications System brings the benefits of converged IP services to midmarket businesses and enterprise branch offices. The Cisco 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 Cisco 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.
Cisco 4-Port FXS/DID VIC with Caller ID Support
To keep up with the rapidly changing business environment in the Internet economy, businesses need cost-effective yet scalable communication network solutions that integrate seamlessly with traditional voice networks as well as the Internet. The Cisco Multiservice Route Processor (MRP) for the Cisco ICS 7750 is flexible in that it can provide the connection to voice networks or to the Internet based on the type of interface the customer requires. The result of combining the MRP with the high-density analog voice interface card (VIC) is a cost-effective yet scalable analog voice service solution that meets the demanding needs of today's customer.
Product Description: Cisco 4-Port FXS/DID VIC
The high-density Cisco 4-Port FXS/DID VIC can support up to four foreign-exchange-station (FXS) ports for directly connecting phones or fax machines, or it can be used to connect up to four direct-inward-dial (DID) analog trunks, providing customers the flexibility they need for their unique business environment (refer to Figure 1). Each port on the Cisco 4-Port FXS/DID VIC is selectable for use in either FXS or DID mode. Because the Cisco 4-Port FXS/DID VIC is the same size as the existing 2-port voice/WAN interface cards (VWICs), it can slide into either one of the two VWIC slots located on the MRP card. Thus ,when installing two Cisco VIC-FXS/DID cards within a single MRP, any combination of up to eight FXS or DID ports can be supported.
DSP Requirements for the Cisco 4-Port FXS/DID VIC
Within the Cisco ICS 7750 System, the medium-complexity analog digital-signal-processor (DSP) image is the factory default for supporting the Cisco 4-Port FXS/DID VIC. This DSP image provides support for four voice channels (of G.711, G.729, or G.726) for each DSP chip. For example, the Cisco PVDM-4 DSP Module has one DSP chip and is, therefore, capable of supporting four voice channels on the Cisco 4-Port FXS/DID VIC. The medium-complexity analog DSP software image supports four channels of G.711, G.729, G.726, fax relay, or modem or fax pass-through, and it provides support for 32-msec echo cancellation per DSP chip.
The Cisco 4-Port FXS/DID VIC also supports the high-complexity analog DSP software 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 Cisco PVDM-8 Module (two DSP chips) is required to support four voice channels on the Cisco 4-Port FXS/DID VIC. The high-complexity analog DSP image supports two channels of G.711, G.729, G.726, G.723.1, fax relay, or modem or fax pass-through, and it provides support for 32-msec echo cancellation per DSP chip.
