DXC-2

E1 to T1 Converter and Timeslot Cross Connect

RAD’s DXC-2 E1 to T1 converter and timeslot cross-connect enables both low density conversion between T1 and E1 data and signaling (24 timeslots) and timeslot swapping between two devices operating at the same speed.

The DXC-2 E1 to T1 converter and timeslot cross-connect is a configurable unit, enabling the user to link any incoming 64 kbps timeslot to any outgoing 64 kbps timeslot. Configuration can be performed during system operation without any service disruption.

Transparent T1/E1 conversion for efficient access to international offices

Compact device saves space in communications cabinets

The DXC-2 E1/T1 E1 to T1 converter and timeslot cross-connect enables conversion between one E1 signal and one T1 signal (24 timeslots). For applications requiring timeslot swapping between two devices operating at the same speed, the unit can also be ordered with two ports of the same type (i.e., two E1 or two T1 ports). An optional built-in LTU (E1) or CSU (T1) is available on either port.

A user-programmable connection table defines the connection of any 64 kbps incoming timeslot to any outgoing timeslot. The DXC-2 E1 to T1 converter and timeslot cross-connect can also perform the required A-law/μ-law and signaling conversion in compliance with E1 and T1 standards. The E1-to-T1 conversion method can be soft-selected to comply with ITU G.802.

Diagnostic loopback support for E1/T1 interfaces includes loopback towards the local or remote DTE.

Multiple clock modes

Several clock modes cover all timing possibilities for the E1/T1 interface. These include internal clock and loopback timing for either the E1 or T1 interface.

The E1 interface complies with ITU G.703, G.704, G.732 and G.823, and supports both two and 16 frames per multiframe with or without CRC-4. Line code is HDB3.

The T1 interface complies with AT&T TR-62411 and ANSI T1.403 requirements, and supports both D4 or ESF framing formats and AMI line code. Zero suppression is selectable between transparent transmission, B7ZS or B8ZS.

Setup, control and diagnostics can be performed via the front panel or an ASCII terminal.
