This flexible, multiservice solution supports multiple data, voice, and integrated data and voice applications, facilitating the migration from data only or channelized data and voice to packet voice solutions and simplifying deployment, management, and sparing.

INTRODUCTION

The Cisco ® Second-generation 1- and 2-port T1/E1 Multiflex Trunk Voice/WAN Interface (MFT VWIC2s) support data and voice applications on the Cisco 1721 (data only), 1751 and 1760 Modular Access Routers, the Cisco 2600XM Multiservice Router, the Cisco 2691 Multiservice Platform, the Cisco 3662 Telco Versatile DCN Access Platform, the Cisco 3725 and 3745 Multiservice Routers, and the Cisco 1841 (data only), 2801, 2811, 2821, 2851, 3825, and 3845 Integrated Services Routers. The Cisco MFT VWIC2 combines WAN-interface-card (WIC) and voice-interface-card (VIC) functions to provide unparalleled flexibility, versatility, and investment protection through its many uses. Customers who choose to integrate data and voice in multiple steps preserve their investment in a T1/E1 WAN interface because the Cisco MFT VWIC2 cards can be reused in packet voice applications. The 2 port T1/E1 MFT VWIC2 is shown below.

Figure 1. Cisco 2-Port T1/E1 MFT VWIC2 (part number VWIC2-1MFT-T1/E1)

The Cisco MFT VWIC2 interface cards add numerous improvements over the Cisco 1- and 2-port T1/E1 Multiflex Voice/WAN Interface Cards (MFT VWICs). The MFT VWIC2 cards have an onboard slot for a Cisco MFT Dedicated Echo Cancellation (ECAN) Module (part number EC-MFT-32 or EC-MFT-64), offering an enhanced echo-cancellation capability for demanding network conditions. The T1/E1 MFT VWIC2 cards support both T1 and E1, providing additional flexibility in configuring the Cisco MFT VWIC2s for supporting T1, fractional T1, E1, and fractional E1 for both voice and WAN applications. All MFT VWIC2 modules now include the drop-and-insert multiplexing capability, which eliminates costly external third-party channel service units/data service units (CSUs/DSUs) and drop-and-insert multiplexers. The Cisco 2-port MFT VWIC2s also can enable each port to be clocked from independent clock sources for data applications. This independent clocking capability is not supported for voice applications or with the Cisco ATM/Voice Advanced Integration Modules (part number AIM-ATM, AIM-VOICE-30, AIM-ATM-VOICE-30).
The Cisco MFT VWIC2 cards can either be inserted into the WIC, VWIC and high-speed WIC (HWIC) slots on the supported Cisco 1721, 1751, 1760, 1841, 2600XM, 2691, 2801, 2811, 2821, 2851, 3662, 3725, 3745, 3825, and 3845 access routers, or they can be used in the VWIC slot(s) on the Digital T1/E1 Packet Voice Trunk Network Module (NM-HDV), IP Communications High-Density Digital Voice/Fax Network Modules (NM-HDV2), IP Communications High-Density Digital Voice NM with 1 T1/E1 (part number NM-HDV2-1T1/E1), IP Communications High-Density Digital Voice NM with 2 T1/E1 (part number NM-HDV2-2T1/E1), 2 slot IP Communications Enhanced Voice/Fax Network Modules (NM-HD-2VE), 2 WAN Card Slot Network Module (NM-2W), 1 10/100 Ethernet 1 4/16 Token Ring 2 WAN Card Slot NM (NM-1FE1R2W), 1 10/100 Ethernet 2 WAN Card Slot Network Module (NM-1FE2W-V2), and 2 10/100 Ethernet 2 WAN Card Slot Network Module (NM-2FE2W-V2) when used with a supported access router.
The Cisco MFT VWIC2 cards are offered in single- and dual-port versions, which can be used and then redeployed as network requirements change, thereby addressing several applications:

T1/E1 data---The Cisco 1- and 2- port T1/E1 MFT VWIC2 versions act as a WIC, supporting T1, fractional T1, E1, (including structured G.703 with G.704 framing), fractional E1, and E1structured G.703 applications. To simplify remote management, these MFT VWIC2 cards integrate a fully managed DSU/CSU for T1 deployments and a fully managed DSU for E1 deployments.

E1/G.703 data---The Cisco 1- and 2- port G.703 MFT VWIC2 versions act as a WIC, supporting T1, fractional T1, E1 (including structured G.703 with G.704 framing), fractional E1, and unstructured E1 (G.703) applications. To simplify remote management, the G.703 version includes a fully managed DSU. The G.703 versions also support all the capabilities on the T1/E1 versions.

T1/E1 packet voice---The Cisco 1- and 2- port T1/E1 MFT VWIC2 (voice and WAN) versions act as a VIC, supporting packet voice applications by providing T1, fractional T1, E1, and fractional E1 connections to private branch exchanges (PBXs) and central offices, thereby enabling new services and reducing voice and fax toll charges.

Mixed data and packet voice---The Cisco MFT VWIC2 interface cards can simultaneously support both data and voice, reducing the complexity and number of network components and facilitating a graceful migration to bandwidth-efficient packet voice.

Mixed data and packet voice with drop and insert---The Cisco MFT VWIC2 cards can be deployed as a T1/E1 drop-and-insert multiplexer with integrated DSUs/CSUs, reducing the complexity of the network and the cost of the central-office ports by efficiently combining time-division multiplexing (TDM) voice (PBX), IP voice, and data on the same trunks. Note the Cisco 1721, 1751 and 1760 support drop and insert between two ports over a single VWIC2 card while Cisco 2800 and 3800 ISR routers supports drop and insert between two ports over a single VWIC2 card and two ports over two different VWICs.

• Offers easy migration to bandwidth-efficient packet voice, enabling new services

Customers who choose to integrate data and voice in stages to preserve their investment in WAN interfaces. For example, the Cisco MFT VWIC2 can support data-only applications as a WAN interface, and then be reused to integrate data and voice with the drop-and-insert multiplexer function or configured to support packetized voice (voice over IP [VoIP] or voice over Frame Relay [VoFR]) when installed in the Digital T1/E1 Packet Voice Trunk Network Module (NM-HDV), 2 slot IP Communications Enhanced Voice/Fax Network Module (NM-HD-2VE), or IP Communications High-Density Digital Voice/Fax Network Module (NM-HDV2), IP Communications High-Density Digital Voice NM with 1 T1/E1 (part number NM-HDV2-1T1/E1), IP Communications High-Density Digital Voice NM with 2 T1/E1 (part number NM-HDV2-2T1/E1).

APPLICATIONS

Packet Voice Solutions: PBX and Central-Office Connectivity

The Cisco MFT VWIC2 interface cards, through its digital T1/E1 ports, supply PBX and public-switched-telephone-network (PSTN) connectivity for the Digital T1/E1 Packet Voice Trunk Network Module (NM-HDV), 2 slot IP Communications Enhanced Voice/Fax Network Modules (NM-HD-2VE), IP Communications High-Density Digital Voice/Fax Network Modules (NM-HDV2), IP Communications High-Density Digital Voice NM with 1 T1/E1 (part number NM-HDV2-1T1/E1), IP Communications High-Density Digital Voice NM with 2 T1/E1 (part number NM-HDV2-2T1/E1), and access routers with on-board VIC/WIC/HWIC slots. The NM-HDV, NM-HD-2VE, NM-HDV2, NM-HDV2-1T1/E1, NM-HDV2-2T1/E1, and access routers support H.323-, Session Initiation Protocol (SIP)-, Media Gateway Control Protocol (MGCP)-, and Skinny Client Control Protocol (SCCP)-based VoIP-, FRF.11-, and FRF.12-based VoFR, and ATM Adaption Layer 5 (AAL5)-based voice-over-ATM (VoATM) industry standards.

Note: For each of these packet voice applications (VoIP, VoFR, or VoATM), an appropriate WIC also is required.

Packet Voice Solutions: Echo Cancellation for Demanding Network Conditions

The Cisco MFT VWIC2 interface cards have an onboard slot for a 32- or 64-channel Cisco MFT Dedicated ECAN Module (part number EC-MFT-32 or EC-MFT-64) (see Figure 2). These optional daughter cards provide a dedicated hardware resource that runs the Cisco Enhanced ITU-T G.168 ECAN feature. The processing and memory resources of the dedicated ECAN module help enable configuration of the echo canceller with predefined settings and an extended 128-ms echo tail buffer, providing a robust echo-cancellation performance for demanding network environments. The 32- and 64-channel configurations of the dedicated ECAN modules match the requirements of the Cisco 1- and 2-port MFT VWIC2 cards, respectively.

Figure 2. Cisco 2-Port T1/E1 MFT VWIC2 (part number VWIC2-2MFT-T1/E1) with an Optional 64-Channel MFT Dedicated ECAN Module (part number EC-MFT-64)

Data Solutions: 1- and 2-Port T1/E1 WIC with Integrated DSU/CSU

The Cisco MFT VWIC2 interface cards simplify branch-office connectivity by integrating the functions of a router, T1/E1, and fractional T1/E1 serial interface with a fully managed DSU/CSU.
When used for "data-only" WAN connectivity, the Cisco MFT VWIC2 cards support numerous functions, including Cisco IOS ® Software Command-Line Interface (CLI)-initiated loopback control, similar to the popular 1 Port T1/Fractional T1 DSU/CSU WAN Interface Card (part number WIC-1DSU-T1). Additionally, the MFT VWIC2 also is offered in dual-port versions, including dual T1/E1 configurations, enabling increased WAN port density in Cisco 1800, 2800 and 3700 series and Cisco 3800 routers and supported Cisco 1700, 2600 and 3600 series access routers. The T1/E1 MFT VWIC2 versions include integrated DSU functions for E1 deployments and integrated CSU and DSU functions for T1 deployments, simplifying remote network management.
The Cisco 2-port MFT VWIC2 interface cards increase configuration flexibility on Cisco Systems ® multiservice access routers, eliminating the need for two single-port T1/E1 WICs. Increasing the T1/E1 port density in a single WIC or HWIC slot helps enable applications such as local serial aggregation with the 2-port high-speed serial WAN Interface Card or 2-port asynchronous/synchronous serial WAN Interface Card (part number WIC-2T or WIC-2A/S), or ISDN backup with the 1 Port ISDN BRI S/T WAN Interface Card (part number WIC-1B-S/T-V3) or the 1 port ISDN with NT-1 WAN Interface Card (part number WIC-1B-U-V2).
The Cisco MFT VWIC2 cards also support a channelized capability where the T1 or E1 service can be flexibly split into two or more fractional channel groups. Thus a single physical port can provide connection to multiple sites. ( Note: If this mode is chosen, only a single port can be supported in each WIC slot.)
The Second-generation 1- and 2-port G.703 Multiflex Trunk voice/WAN Interface Cards (product numbers VWIC2-1MFT-G703 and VWIC2-2MFT-G703) support not only unstructured E1 (G.703) but also all the features of the other Cisco MFT VWIC2 cards, including drop and insert. Additional flexibility is provided on the 2 port G.703 Multiflex Trunk voice/WAN Interface Cards with the capability to configure one port for unstructured E1 (G.703) while configuring the other for standard framed E1.

Multiplexed Data and Voice Solutions: 2-Port T1/E1 Drop-and-Insert Multiplexer with Integrated DSU/CSU

The Cisco 1- and 2-port MFT VWIC2 interface cards simplify branch-office connectivity by helping enable a Cisco 2800, 3700, or 3800 and select Cisco 2600 and 3600 routers to consolidate the functions of a router, a fully managed drop-and-insert multiplexer, and a fully managed DSU/CSU into a single box. (It is possible to use two Cisco 1-port MFT VWIC2 interface cards for supporting the drop-and-insert feature. Generally a Cisco 2-port MFT VWIC2 is more appropriate because 2 ports are required.) Typically a drop-and-insert multiplexer is used for channelized (that is, TDM) integration of data and voice onto a single T1, fractional T1, E1, or fractional E1 connection to the central office. Sharing a line can significantly reduce costs over those of two separate physical lines to the central office. Although the normal use is for data and voice sharing of a T1 or E1 service, the drop-and-insert capability also can be used for video and data, or data and data sharing of the service.
Moreover, the integrated drop-and-insert capability enhances system availability by allowing the Cisco IOS Software to be reloaded while maintaining TDM switching.

Figure 3. Drop and Insert to Share a T1/FT1 or E1/FE1 Service between Data and TDM Voice

To illustrate, consider the example of a PBX with a T1 interface that needs to support a maximum of 10 simultaneous calls. With 24 DS-0 channels in a T1 service (1.544 Mbps), this leaves 14 DS-0 channels or 896 kbps of bandwidth for data from the router (14 x 64 kbps). The number of DS-0 channels assigned for PBX calls and the remainder that are available for use with router data are fully configurable (statically, not dynamically). In the case of an E1 service, 30 DS-0 channels are available for division between voice and router data.
In this example one port of the Cisco 2-port T1/E1 MFT VWIC2 is connected to the PBX and the other port is connected to the central office. The 10 DS-0 channels from the PBX are TDM switched to the "central-office port," and this switching is done on the MFT VWIC2 itself. The configuration of this TDM switching is flexible so that DS-0 channels on the "PBX port" do not have to be mapped to DS-0 channels with the same time slots on the central-office port. The remaining 14 DS-0 channels on the MFT VWIC2 central-office port terminate through the backplane connector of the VWIC2 on the router as a single aggregate channel group. The 14 DS-0 channels are not individually addressable by the router as a channelized service, but can be split into two or more channel groups.
The drop-and-insert function is included in all the Cisco MFT VWIC2 interface cards. The term "drop and insert" is normally used when router data (or data from another data device) is multiplexed with voice calls. A more generic term for "drop and insert" is "digital cross-connect." On Cisco 2600/3700 access routers, Digital cross-connecting of voice channels is only supported by the Cisco MFT VWIC2 when inserted into the Digital T1/E1 Packet Voice Trunk Network Module (NM-HDV), 2 slot IP Communications Enhanced Voice/Fax Network Modules (NM-HD-2VE) or IP Communications High-Density Digital Voice/Fax Network Modules (NM-HDV2), IP Communications High-Density Digital Voice NM with 1 T1/E1 (part number NM-HDV2-1T1/E1), and IP Communications High-Density Digital Voice NM with 2 T1/E1 (part number NM-HDV2-2T1/E1). For example, a single T1 connection from a PBX to the PBX port on the MFT VWIC2 can be divided between DS-0 channels that go to the Digital T1/E1 Packet Voice Trunk Network Module (NM-HDV) for packetized voice (for example, VoIP) and DS-0 channels that are TDM switched to the central-office port of the MFT VWIC2 for standard circuit-switched voice connectivity. On Cisco 2800/3800 integrated services routers, digital cross-connecting of channels is supported by the Cisco MFT VWIC2 when inserted into an HWIC slot or any of the network modules listed above.

Analog Cross Connect Solution

The time-division multiplexing (TDM) DS0 channels can be cross-connected with analog voice ports to create an analog cross connect solution. This capability is supported on the 1760, 2800 and 3800 series routers. It can also be supported the supported 26, 37 and 3700 access routers when both ports are on the same network module (NM-HD-2VE, NM-HDV2, NM-HDV2-1T1/E1, NM-HDV2-2T1/E1).
