• Supports M23 DS3, C-bit DS3, G.751 E3, and G.832 E3 facilities
• Mapping/demapping of three DS3/E3 tributaries to/from STS-3/STM-1 through STS-1 or AU-3 or TU-3/AU-4
• Fully integrated and compliant DS3/E3 mapper/demapper and synchronizers/desynchronizers per
Telcordia, ANSI, and ITU standards
• High speed DS3/E3/STS-1/STS-3 overhead insertion/extraction with full access to all overhead bytes
• Full-featured DS3/E3/STS-1/STS-3 defect and performance monitoring (PM) support Large PM counters
for accumulation intervals up to one second
• Loopback capabilities at both STS-3/STM-1 side and line DS3/E3 side
• Dual STS-3/STM-1 155.52Mbps serial interfaces with receive clock recovery and transmit clock synthesis
• From a single reference clock the CLAD (cLock rate adapter) generates clock references for DS3
(44.736MHz), E3 (34.368MHz), and/or STS-3/STM-1 reference (77.76/19.44MHz)
