Overview
The Cisco VWIC-2MFT-T1-DIR and VWIC-2MFT-E1-DIR Voice/WAN Interface Cards support data
applications on the Cisco MWR 1941-DC Mobile Wireless Edge Router for T1/E1 networks. These
cards are dual-port, T1/Fractional T1 or E1/Fractional E1, Drop and Insert Multiplexers with integrated
T1 CSU/DSUs or E1 DSUs. The T1 version supports framed and unframed traffic, and the E1 version
supports framed traffic and unframed traffic that conforms to the ITU-T G.703 standard for full 2.048
Mbps bandwidth.
The Drop and Insert multiplexer diverts (drops) streams of an aggregate Time Division Multiplexed
(TDM) traffic stream, and introduces (inserts) different streams for transmission in the time slots that
were previously occupied by the dropped streams. Each VWIC supports a limited channelized capability
where the T1 or E1 can be flexibly split into two fractional channel groups, one on each port or two on
one port. The switching operation can be maintained through router restarts and reloads of Cisco IOS
software.

Each VWIC supports a limited channelized capability where the T1 or E1 can be flexibly split into two fractional channel groups, one on each port or two on one port. The switching operation can be maintained through router restarts and reloads of Cisco IOS software. - Page 2 Each card also features protection switch solid state relays on the line interfaces, which together with redundancy logic and relay control added in a Cisco IOS feature set on the MWR 1941-DC router, can be used to provide T1/E1 Protection Switching between redundant routers in applicable implementations.

You can determine whether your equipment is causing interference by turning it off. If the interference stops, it was probably caused by the Cisco equipment or one of its peripheral devices. If the equipment causes interference to radio or television reception, try to correct the interference by using one or more of the following measures: Turn the television or radio antenna until the interference stops. - Page 9 How you connect the ports of the T1/E1 Multiflex VWIC depends on whether you are using the Cisco MWR 1941-DC router in a redundant or a non-redundant configuration. Whether you are using the Cisco MWR 1941-DC router in a redundant or non-redundant configuration depends on the implementation of the router. For information on MWR 1941-DC router implementations, see the Cisco MWR 1941-DC Mobile Wireless Edge Router Software Configuration Guide.
- Page 10 If you choose to use the T1/E1 Multiflex VWIC in a non-redundant configuration, you must close the Note relays on the card using the standalone subcommand. For more information, see the “Cisco MWR 1941-DC Mobile Wireless Edge Router Software Configuration Guide.”...

For example, RX TIP and RX RING must form a single twisted pair. • All unused twisted pairs should be cut flush on both ends of the cable. Any unused wire in a twisted pair where one wire is in use should be cut flush at both ends.

Page 12: Understanding The Leds
Understanding the LEDs The T1/E1 Multiflex VWIC has six LEDs (three for each port) as listed in Table Table 2 T1/E1 Multiflex Trunk Interface Card LEDs Description Color LP LED On means that a loopback or line state is Amber detected or is manually set by the user. - Page 13 Aviso Antes de executar um dos seguintes procedimentos, certifique-se que desligou a fonte de alimentação de energia do circuito de corrente contínua. ¡Advertencia! Antes de proceder con los siguientes pasos, comprobar que la alimentación del circuito de corriente continua (CC) esté cortada (OFF). Varning! Innan du utför någon av följande procedurer måste du kontrollera att strömförsörjningen till likströmskretsen är bruten.
