The DXC-30E is a modular multiservice access node providing non-blocking DS0 cross connect for up to 240 lines. It is designed to provide a high port density solution for xDSL applications. The DXC-30E features optional redundant AC or DC power supplies and two redundant common logic modules.Plug-in interface modules can accommodate up to 16 links (see description of the additional special modules following). Support is provided for all DXC family modules: n x 56/64 kbps, ISDN, E1, T1, E3, T3, T3/G.747 and STM-1 over fibre, copper, IDSL, HDSL and SHDSL. An inverse multiplexing module with rate capacity of up to 15.7 Mbps is also available.

Cross connect groomer and broadcast

The DXC-30E allows the same flexibility between ports as in the DXC family.

T1/E1 converter

The DXC-30E can convert up to 17 E1/T1 ports. A-law/µ-law and signaling conversion are performed according to E1 and T1 standards.

E3, T3, T3/G.747 and STM-1 multiplexer modules

The DXC-30E supports all DXC family multiplexer modules.

Redundancy

The redundancy features of the DXC-30E are identical to those of the DXC-30.

Basic unit

The 6U high chassis can support up to 240 ports.The basic unit includes one power supply, one common logic module and 15 I/O slots for the plug-in interface modules. Optional secondary power supply and/or common logic can be ordered at any time for full or partial system redundancy.The DXC-30E supports all the features and modules of the DXC family, but in an extended 6U high enclosure.

Setup, management and diagnostic tools

The DXC-30E supports all the features and management capabilities of the DXC family.

Modules

The DXC-30E offers the same features and supports all the I/O modules of the DXC-30: DE1B, D4E1, D8E1, DT1B, D4T1, D8T1, DE3, DT3, DT3/G.747, DFSTM-1, DIM, D8U, D8SL and DHS.Dedicated modules for the DXC-30E: - DHL HDSL module provides the same features as in the other DXC chassis, but occupies only one I/O slot - D16U high density 16-port module enables IDSL extension to remote modems at ranges up to 5.5 km (3.4 miles) or ISDN (U interface) 2B+D channel transmission at ranges up to 5.5 km (3.4 miles), at data rates up to 128 kbps per port

Applications

In addition to supporting all the typical DXC applications, the DXC-30E is ideal for xDSL applications that require many SHDSL, HDSL, IDSL or ISDN services. When loaded with the higher port density cards or single-slot cards (DHL), the capacity of the DXC-30E unit increases to up to 80 SHDSL ports, 28 HDSL ports or 224 IDSL ports (14 D16U modules and one STM-1/E3/T3 module).
