Applications

Provides connection of terminal equipment (DTE) with n x 64kbit/s X.21/V.11 interface to telecommunication network via multiplexers FM2x2 and FM-MSAN (DCE)

Independent selection of number (1 to 31) of 64 kbit/s channels for each interface

Basic functions

• 4 n x 64kbit/s X.21 interfaces on one board
• Programmable position in multiplex for each n x 64 kbit/s channel, independent
• Number of 64 kbit/s channels, n per interface can be 1, 2,..., 31
• Independent selection of X.21 interface type: codirectional or contradirectional
• Byte Timing signal (B) is available for contradirectional interface type
• Selectable Byte Timing signal type: time slot (byte) or PCM frame of FM2x2 and FM-MSAN
• Codirectional interface type can be referent clock source for multiplexers FM2x2 and FM-MSAN
• Asymmetric capacity is possible for codirectional interface type
• Unused interfaces can be switched off for power saving
• States of near (DCE) and far (DTE) end are displayed by front LEDs
