VMUX-(FUN.DESC)TYPES OF USER INTERFACES WITH VMX-0100

TYPES OF USER INTERFACES WITH VMX-0100

           The following user interfaces are presently supported by VMX-0100:

            ( i )       VF Interfaces

·         E & M (2W)

·         E & M (4W)

·         Loop Incoming Signalling

·         Loop Outgoing Signalling

·         Exchange Interface

·         Subscriber Interface

·         Hot Line Interface

Through a unique design technique all Loop Signalling interfaces are implemented in just three types of cards, thus minimizing the variety of hardware in the VMX-0100.

            (ii)        Data Interfaces

·         G.703, co-directional, synchronous data interface @ 64Kbps.

·         V.35/V.24/V.11/X.21, synchronous/ asynchronous data interface @ 1200-19200 baud.

·         "N" x 64Kbps, V.35/V.24/V.11/X.21 user configurable, synchronous data interface with N=1 to 30.

·         ISDN Digital Subscriber line (IDSL) supporting 64/128 Kbps.

·         N * 64, G.703 / Fractional E1 Interface.

·         Additional four channels for Teleprinter Data, 50/100 baud on the spare bits.

 64Kbps support is available through GDT Card, which supports four 64Kbps G703 Co-directional Data.

Low speed V.35/V.24/V.11/X.21 support is available through a UDT Card that provides four low speed synchronous  /asynchronous ports of 1200/ 2400/ 4800/ 9600/ 19200 bps in a card.
