XMP1-SL Compact 1HU Access Multiplexer

XMP1-SL Compact 1HU Access Multiplexer

The Transport Gateway XMP1-SL (Slim Line) is a compact, space saving, universal 1 HU cross-connect which provides in its basic configuration grooming and consolidation of 8x E1. It hosts 1 slot to equip an original XMP1 module and connectors for 2 additional data sub modules. It combines the advantages of today’s successful XMP1 platform with its compact design. This guarantees a seamless integration in existing XMP1 networks as well as any other applications. The end-to-end management platforms ServiceOn XMP1 (SOX) and ServiceOn Access (SOA) fully supports the setup, configuration and monitoring of the XMP1 networks. Local management is supported by LCT.


  • 1 HU cross-connect
  • Fully non-blocking 8/64k cross-connect
  • 8 x E1 (75/120 ohm)
  • Up to 4 data interfaces (V.x/G.703)
  • Up to 2 Ethernet Interfaces 10/100 BaseTx
  • 1 universal slot for any XMP1 module
  • Managed by ServiceOn XMP1 (SOX) and ServiceOn Access (SOA)
  • High availability by traffic protection and redundant power feeding
  • Well suited and optimized for transport and mobile networks

The XMP1-SL covers any kind of network topology, supporting the whole range of private and public transport networks such as:

  • Traffic routes (railways, waterways, motorways)
  • Municipal utilities (gas, water, electricity)
  • Power plants
  • Pipeline companies
  • Common carriers (Telcos)
  • Mobile operator
  • Security and military applications (e.g. air traffic control)
  • Blue Light Networks (police, fire brigade, first aid)

Basic configuration:

  • 8x E1
  • Redundant Power Feeding
  • Network Management, SOX or SOA; Q(LAN) over TCP/IP
  • Local Management via RS232
  • Clocking T3/T4 and derived from any E1 signal, supported by clock priorities network wide
  • Alarm contacts A-alarm, B-alarm and additional 2 out and 3 in
  • Optional 2 modules V.11/V.35/V.24/WT or G.703co./contra
