Multiflex Trunk Interface Cards

Multiflex trunk interface cards support generic 1- or 2-port T1 or E1 trunk interfaces for voice, data, and
integrated voice and data applications. These cards provide basic structured and unstructured service for
T1 or E1 networks.
They can be used as trunk interfaces for voice and data services, as fractional n x 64-kbps service for
WANs (Frame Relay or leased line), or for time-division multiplexing (TDM) drop-and-insert (voice and
data integration) services.
Multiflex trunk interface cards provide voice and data access to the PSTN domain through TDM ports,
and include an integrated channel service unit/data service unit (CSU/DSU).
Some 2-port multiflex trunk interface cards also support the drop-and-insert process, which adds data to
a T1 or E1 data stream, or terminates data from a T1 or E1 data stream to other devices connected to the
drop-and-insert equipment.
When both ports on a VWIC-2MFT-T1, VWIC-2MFT-E1, VWIC-2MFT-G703, or VWIC-2MFT-E1-DI
Caution
interface card are configured as clock source line, then they must be set to the same clock source. If they
are not set to the same clock source, timing slips can occur. Each port on the VWIC2-2MFT-T1/E1 and
VWIC2-2MFT-G703 interface cards can be set to independent clock sources for data applications.

Caution
connect the 2-port E1 multiflex trunk interface card with G.703 support (VWIC-2MFT-G703) only to
intra-building or non-exposed wiring or cabling. The intrabuilding cable must be shielded and the shield
must be grounded at both ends.
