  • Cost effective


Aries Telecom offers next generation SDH multiplexers to provide multiple services from E1 tributaries (software configurable as E1) and 1 E3/DS3 tributaries (software configurable as E3 or DS3) or an 8 port 10/100Base-T Ethernet interfaces.

The STM-1, VCL100CPE (with E1) and with one tributary interface card (E3 / DS3 / Ethernet) is an ultra-compact and cost-effective customer premises bandwidth provisioning STM-1 SDH multiplexer equipment designed to meet low or medium capacity bandwidth service demands.

Following tributary choices are available:

  • E1s (standard part of equipment / chassis) with

  • (any one of the following) E3 or DS3 or 10/100 BaseT Ethernet

The chassis is 19" rack or wall mountable as per customer requirements. This unique product supports end-to-end provisioning and management of voice and data services across all the segments of the optical network - from the customer premises to the core. It combines innovative optical networking software with the intelligence of SDH to deliver a flexible solution to today's service providers. The VCL100CPE can be configured as a Terminal Multiplexer (TMUX) or an Add-Drop Multiplexer (ADM), with E1, E3, DS3 or 10/100 Ethernet Interface service interfaces and trunk interfaces at STM-1 rate.


  • Cost-effective multi-service box for customer premises

  • Support for terminal multiplexer and add-drop multiplexer configurations

  • Support for E1 / DS1, E3 / DS3 and 10/100BaseT tributaries

  • Support for MSP and SNCP protection

  • Complete integration into NMS for a true end-to-end network solution

  • -48V DC powered

  • 19" rack or wall mountable.


  • Power failure interrupt and power hold for graceful shutdown

  • Laser failure detection

  • Laser on/off control for safety requirements

  • Real time clock (RTC)

  • Disk and Flash for non-volatile storage of configuration

  • LED test button / signal

  • Ethernet and craft interfaces for NMS / External control channel

  • Order-wire capability

  • Alarm contacts

  • Provision for separate System Reset and Processor Reset

  • External power inputs

  • E1 drops or E3 / DS3 or 10/100 Ethernet tributaries.

Redundancy and Protection

  • Software redundancy for terminating and restarting critical processes with no service disruption

  • High network resiliency using robust protection mechanisms like 1+1 MSP and SNCP.
