Cisco 7200 and Cisco 7500 Series Routers

Cisco 7200 and Cisco 7500 series routers support multimedia routing and bridging with a wide variety

of protocols and media types. The Cisco 7000 family versatile interface processor (VIP) is based on a

RISC engine optimized for I/O functions. To this engine are attached one or two port adapters or

daughter boards, which provide the media-specific interfaces to the network. The network interfaces

provide connections between the routers’ peripheral component interconnect (PCI) buses and external

networks. Port adapters can be placed in any available port adapter slot, in any desired combination.

T1/E1 high-capacity digital voice port adapters for Cisco 7200 and Cisco 7500 series routers allow

enterprises or service providers, using the equipped routers as customer premise equipment, to deploy

digital voice and fax relay. These port adapters receive constant bit-rate telephony information over

T1/E1 interfaces and can convert that information to a compressed format for transmission as voice over

IP (VoIP). Two types of digital voice port adapters are supported on Cisco 7200 and Cisco 7500 series

routers: two-port high-capacity (up to 48 or 120 channels of compressed voice, depending on codec

choice), and two-port moderate capacity (up to 24 or 48 channels of compressed voice). These

single-width port adapters incorporate two universal ports configurable for either T1 or E1 connection,

for use with high-performance digital signal processors (DSPs). Integrated CSU/DSUs, echo

cancellation, and DS0 drop-and-insert functionality eliminate the need for external line termination

devices and multiplexers.

Configuration

Cisco IOS release being used.
