Platform-Specific Digital Voice Hardware
This section briefly describes digital voice hardware on the following platforms:
• Cisco 2600 series and Cisco 3600 series routers
• Cisco MC3810 multiservice concentrator
• Cisco AS5300 universal access server
• Cisco AS5800 universal access server
• Cisco 7200 series and Cisco 7500 series routers
Note For current information about supported hardware, see the release notes for the platform and
Cisco IOS release you are using.
Cisco 2600 Series and Cisco 3600 Series Routers
Digital voice hardware on Cisco 2600 series and Cisco 3600 series modular access routers includes the
high-density voice (HDV) network module and the multiflex trunk (MFT) voice/WAN interface card
(VWIC). When an HDV is used in conjunction with an MFT and packet voice DSP modules (PVDMs),
the HDV module is also called a digital packet voice trunk network module. The digital T1 or E1 packet
voice trunk network module supports T1 or E1 applications, including fractional use. The T1 version
integrates a fully managed data service unit/channel service unit (DSU/CSU), and the E1 version
includes a fully managed DSU. The digital T1 or E1 packet voice trunk network module provides
per-channel T1 or E1 data rates of 64 or 56 kbps for WAN services (Frame Relay or leased line).
Digital T1 or E1 packet voice trunk network modules for Cisco 2600 and 3600 series routers allow
enterprises or service providers, using the voice-equipped routers as customer premise equipment
(CPE), to deploy digital voice and fax relay. These network modules receive constant bit-rate telephony
information over T1 or E1 interfaces and convert that information to a compressed format so that it can
be sent over a packet network. The digital T1 or E1 packet voice trunk network modules can connect
either to a PBX (or similar telephony device) or to a CO to provide PSTN connectivity. One digital T1
or E1 packet voice trunk network module can be installed in a Cisco 2600 series router or in a Cisco
3620 router. A Cisco 3640 router can support three network modules, and a Cisco 3660 router can
support up to six network modules.
