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 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.

Note For information on the Cisco MWR 1941-DC router implementations and Cisco IOS software available

for those implementations, see the Cisco MWR 1941-DC Mobile Wireless Edge Router Software
Configuration Guide.

The Cisco MWR 1941-DC router provides three WAN interface slots, which allows support for 6
T1/E1s.

Electrical Equipment Guidelines

Follow these basic guidelines when working with any electrical equipment:

• Before beginning any procedures requiring access to the chassis interior, locate the emergency

power-off switch for the room in which you are working.

• Disconnect all power and external cables before moving a chassis.

• Do not work alone when potentially hazardous conditions exist.

• Never assume that power has been disconnected from a circuit; always check.

• Do not perform any action that creates a potential hazard to people or makes the equipment unsafe;

carefully examine your work area for possible hazards such as moist floors, ungrounded power
extension cables, and missing safety grounds.

Telephone Wiring Guidelines

Use the following guidelines when working with any equipment that is connected to telephone wiring or
to other network cabling:

• Never install telephone wiring during a lightning storm.

• Never install telephone jacks in wet locations unless the jack is specifically designed for wet

locations.

• Never touch uninsulated telephone wires or terminals unless the telephone line has been

disconnected at the network interface.

• Use caution when installing or modifying telephone lines.

Preventing Electrostatic Discharge Damage

Electrostatic discharge (ESD) damage, which can occur when electronic cards or components are
improperly handled, results in complete or intermittent failures. Port adapters and processor modules
comprise printed circuit boards that are fixed in metal carriers. Electromagnetic interference (EMI)
shielding and connectors are integral components of the carrier. Although the metal carrier helps to
protect the board from ESD, use a preventive antistatic strap during handling.

Following are guidelines for preventing ESD damage:

• Always use an ESD wrist or ankle strap and ensure that it makes good skin contact.

• Connect the equipment end of the strap to an unfinished chassis surface.

• When installing a component, use any available ejector levers or captive installation screws to

properly seat the bus connectors in the backplane or midplane. These devices prevent accidental
removal, provide proper grounding for the system, and help to ensure that bus connectors are
properly seated.

• When removing a component, use any available ejector levers or captive installation screws to

release the bus connectors from the backplane or midplane.

• Handle carriers by available handles or edges only; avoid touching the printed circuit boards or

connectors.

78-15842-01

VWIC-2MFT-T1-DIR, VWIC-2MFT-E1-DIR Installation Instructions

• Place a removed board component-side-up on an antistatic surface or in a static shielding container.

If you plan to return the component to the factory, immediately place it in a static shielding
container.

• Avoid contact between the printed circuit boards and clothing. The wrist strap only protects

components from ESD voltages on the body; ESD voltages on clothing can still cause damage.

• Never attempt to remove the printed circuit board from the metal carrier.

Caution For safety, periodically check the resistance value of the antistatic strap. The measurement should be

between 1 and 10 megohms (Mohms).

FCC Class A Compliance

This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant
to part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful
interference when the equipment is operated in a commercial environment. This equipment generates,
uses, and can radiate radio-frequency energy and, if not installed and used in accordance with the
instruction manual, may cause harmful interference to radio communications. Operation of this
equipment in a residential area is likely to cause harmful interference, in which case users will be
required to correct the interference at their own expense.

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.

• Move the equipment to one side or the other of the television or radio.

• Move the equipment farther away from the television or radio.

• Plug the equipment into an outlet that is on a different circuit from the television or radio. (That is,

make certain the equipment and the television or radio are on circuits controlled by different circuit
breakers or fuses.)

Installing the VWIC-2MFT-T1-DIR, VWIC-2MFT-E1-DIR

In addition to the T1/E1 Multiflex VWIC and the Cisco MWR 1941-DC router, you need the following
items to install and connect your card:

• Number 2 Phillips screwdriver

• ESD-preventive wrist strap

• Appropriate connecting cable

You can install T1/E1 Multiflex VWICs either before or after mounting the router, whichever is more
convenient.

Caution T1/E1 Multiflex VWICs do not support online insertion and removal (hot swapping). Before inserting a

card into the network module or router chassis, you must turn off electrical power and disconnect
network cables.

ground lug.

Warning

Step 2 Remove all network interface cables, including telephone cables, from the front panel.
Step 3 Use either a number 2 Phillips screwdriver or a small flat-blade screwdriver to remove the blank filler

Before performing any of the following procedures, ensure that power is removed from the DC circuit.
To ensure that all power is OFF, locate the circuit breaker on the panel board that services the DC
circuit, switch the circuit breaker to the OFF position, and tape the switch handle of the circuit
breaker in the OFF position.

panel from the network module slot where you plan to install the card. Save the filler panel for future use.

Step 4 Align the card with the guides in the two-slot network module and slide it gently into the slot.
Step 5 Push the card into place until you feel its edge connector mate securely with the connector.
Step 6 Fasten the card’s captive mounting screws into the holes in the network module faceplate using the

Phillips or flat-blade screwdriver.

Step 7 If the router was previously running, reinstall the network interface cables and turn on power to the

router.

Warning

After wiring the DC power supply, remove the tape from the circuit breaker switch handle and
reinstate power by moving the handle of the circuit breaker to the ON position.

Connecting the T1/E1 Multiflex VWIC Card

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.

For redundant configurations, use a Y-cable (as described in Y-Cable Specifications, page 10).

Note HSRP must be configured for redundancy to allow one router to become active (CD LED on) and the

other to become the standby (AL LED on due to no framing).

Step 1 Confirm that both routers are turned off.
Step 2 Connect the end of one of the Y-cable stubs to the T1 or E1 port on the card on the first router.
Step 3 Connect the end of the other Y-cable stub to the T1 or E1 port (using the same type of port as in Step 2)

on the card in the second router.

Step 4 Connect the other end of the Y-cable to the BTS patch or demarcation panel at your site.
Step 5 Turn on power to the routers.
Step 6 Check that the CD LEDs goes on, which means that the card’s internal DSU/CSU is communicating with

the DSU/CSU at the T1 or E1 service provider central office.

For non-redundant configurations, use a straight-through, shielded RJ-48C-to-RJ-48C cable.

Note If you choose to use the T1/E1 Multiflex VWIC in a non-redundant configuration, you must close the

relays on the card using the standalone subcommand. For more information, see the “Cisco MWR
1941-DC Mobile Wireless Edge Router Software Configuration Guide.”

Step 1 Confirm that the router is turned off.
Step 2 Connect one end of the cable to the T1 or E1 port on the card.
Step 3 Connect the other end to the BTS patch or demarcation panel at your site.
Step 4 Turn on power to the router.
Step 5 Check that the CD LED goes on, which means that the card’s internal DSU/CSU is communicating with

the DSU/CSU at the T1 or E1 service provider central office.

Configuring the VWIC-2MFT-T1-DIR, VWIC-2MFT-E1-DIR

For information about configuring the T1/E1 Multiflex VWICs, see the “Cisco MWR 1941-DC Mobile
Wireless Edge Router Software Configuration Guide.”

Y-Cable Specifications

Depending on the Cisco MWR 1941-DC router implementation, the T1/E1 Multiflex VWIC can be used
in a standalone router or in redundant Cisco MWR 1941-DC router configurations. For redundant
configurations, a special Y-cable is required to connect the active and standby routers. The Y-cable
provides a dual E1 or T1 PRI connection.

This section describes the specifications of the Y-cable.

• T1/E1 Multiflex VWIC Y-cables should be made with 4 twisted-pair, shielded, 28-gauge cables.

• The cable length of each stub (from the RJ-48C connector to the junction point) should not exceed

3 inches (76 mm).

• The cable length from junction point to the patch panel is determined by the customer.
