Used Cisco VWIC Interface Card
Part # VWIC-1MFT-E1
 Product
Description: Cisco 1700, 1800, 2600, 2600XM, 2800, 3600, 3700, and 3800 Series Multiflex
Voice WAN Interface Card (VWIC) - 1-Port RJ-48 Multiflex Trunk-E1.
The Cisco 1-Port E1 Multiflex Voice/WAN Interface Card
VWIC-1MFT-E1 supports voice and data applications on the Cisco
1700, 2600, 3600, and 3700 series routers. The 1-Port E1
Multiflex Trunk VWIC is not like the T1 channel service
unit/data service unit (CSU/DSU) (WIC-1DSU-T1).
You can use this multiflex trunk as a voice interface card (VIC)
or as a WAN Interface Card (WIC) (in a WIC slot in the 1700,
2600, 3600, or 3700).
The multiflex trunk provides physical layer E1 access. The host
into which you plug the E1 interface determines the E1 interface
capabilities. When you use the multiflex trunk in a high-density
voice network module, each digital service zero (DS0) time slot
can contain voice calls. The voice network module, and not the
multiflex trunk, determines the E1 signaling capability (E1 R2,
ISDN PRI).
Each multiflex controller can support either one ISDN PRI or E1
channel associated signaling (CAS) or E1 R2 signaling. The
reason for this limitation is that each of these signaling types
uses the same time slot (16) for trunk signaling.
The multiflex trunk, with or without a high-density voice
network module, cannot terminate a modem connection on the
router. When you use the multiflex trunk in the WIC slot of the
2600, you can configure each E1 into a single channel group as a
serial interface.
The 3600 NM-1E2W, NM-1E1R2W, and NM-2E2W support one serial
channel group per WIC slot. Therefore, there is no support for
the VWIC-2MFT-E1. Support is available for the VWIC-2MFT-E1-DI,
but with one serial channel group. The NM-1FE2W, NM-1FE1R2W,
NM-2FE2W, and NM-2W support two serial channel groups per WIC slot.
The VWIC-MFT-E1 receiver operates in a short haul mode and can
recover a 20-decibel (dB) attenuated signal. In order to
translate this to an accurate cable length, you need to know the
cable attenuation characteristics. Typical cable attenuation for
.4 millimeter (mm) wire is 3 dB per 100 meter (m) (measured at
1024 kilohertz
[KHz]). So the maximum cable length for this card is
approximately 600 m. This value includes a 3 dB margin.
