Introduction

The VCL100 STM-1/4 is a modular, and cost effective STM-1/4 SDH multiplexer equipment designed to manage bandwidth and voice & data access services over STM networks. The products are designed to support end-to-end provisioning and management of services across all segments of the optical network. It combines innovative optical networking software with the intelligence of SONET/SDH to deliver a flexible, cost-effective network solution.

Chassis

The VCL100 STM-1/4 is a 19” wide, 10.5” high 14 slot chassis, in a half-depth rack allowing back-to-back arrangement for VCL100 STM-1/4s. This chassis can be installed in both 19” and 23” rack with suitable adapters.

Hardware components

STM-1 Aggregate/Tributary Card

The aggregate/tributary card has STM-1 interfaces. Terminal multiplexer configuration can utilize an STM-1 card. Add-Drop Multiplexer configuration can utilize either 1 STM-1 or 2 STM-1 cards. To provide aggregate card redundancy, additional card be inserted in the second aggregate card slot.

STM-4 Aggregate Card

The aggregate card has a STM-4 interface for terminal multiplexer or add-drop multiplexer applications respectively. To provide aggregate card redundancy for Terminal Multiplexer configuration, additional card be inserted in the second aggregate card slot.

E1 Tributary Card
E1 tributary cards are supported.

E3 Tributary Card
E3 tributary cards are supported.

DS3 Tributary Card
DS3 tributary cards are supported.

10/100 Mbps Ethernet Tributary Card (ETC)

ETC card maps 10/100 Mbps Ethernet data on to VC-12’s with a rate adaptation granularity of 2 Mbps. Each port’s bandwidth is configurable in increments of 2Mbps, based on per port user demand. The aggregate bandwidth from each ETC card is STM-1 line rate (63 VC-12 worth of traffic), or lower.

Power Supply Card (PSU1)

The power to entire chassis is distributed from this card. This is a hot-insertible, hot stand-by current sharing power supply, running off a –36V to –60V DC supply. This would supply power to all the cards. PSU1 can be configured to be redundant.
