Overview
The Cisco DS3 to Vt1.5 MXR Card (part number 800-08720-01) is a high performance interface module that converts a DS3 (Digital Signal level 3) line into a Vt1.5 (Virtual Tributary 1.5) payload for use in Cisco MXR (Multiservice Exchange Routing) platforms. Designed for carrier grade networks, this card provides reliable, low latency transport of voice, video and data services across legacy TDM and modern packet based environments.
Key Features
- Seamless DS3 to Vt1.5 conversion with full compliance to ANSI T1.105 standards
- Supports up to 28 Vt1.5 tributaries per card for flexible bandwidth allocation
- Built-in error detection and correction to maintain data integrity
- Hot-swap capable for zero-downtime maintenance
- Compact form factor fits standard MXR chassis slots
- Low power consumption reduces operational costs
Technical Specifications
- Interface type: DS3 (44.736 Mbps) input, Vt1.5 (1.544 Mbps) output per tributary
- Maximum tributaries: 28 Vt1.5 channels
- Operating temperature: 0 to 55 deg C
- Power supply: 48 V DC, 0.5 A per card
- Dimensions: 1U rack height, standard MXR slot width
- Compliance: ANSI T1.105, ITU G.703, G.704
Applications
The DS3 to Vt1.5 MXR Card is ideal for service providers and enterprises that need to integrate legacy DS3 circuits with modern SONET/SDH or Ethernet networks. Typical applications include:
- Carrier grade voice transport and migration to packet networks
- Video distribution over TDM infrastructure
- Backbone connectivity for regional data centers
- Disaster recovery links that require reliable TDM to packet conversion
- Network aggregation points where multiple DS3 feeds are broken into granular Vt1.5 streams
By delivering a dependable bridge between DS3 and Vt1.5, this Cisco MXR card helps organizations maximize existing investments while preparing for future network evolution.
