Phone: +1 (480) 816-8672 Fax: +1 (480) 816-0115 E-mail: [email protected] Web Site: http://www.oriontelecom.com Updated : July, 2006 Orion Telecom Networks Inc. - 2006 Slide 1 T1 Voice Echo Canceller - 3U (10 per Chassis) Product Overview • • • • • • • Orion Telecom provides robust and cost effective E1 and T1 echo canceller and voice quality enhancement solutions for the long distance, wireline, wireless, (GSM, CDMA), VoIP, satellite and radio communications. The VCL-EC, T1 echo canceller are offered to provide cancellation of 64ms / 128ms (user selectable) echo tails. The echo canceller equipment is compliant to ITU-T G.164, G.165, G.168 (2000 / 2002) requirements for echo cancellation. The echo canceller solutions offers carrier-grade voice quality per AT&T Voice Quality Assessment Lab. The echo canceller supports fax / modem G.164 and G.165 (2100 Hz) tone disable function. The echo canceller is equipped to offer redundant power supply (optional). The equipment offers RS232 serial interface for configuration through a PC COM Port, and an Ethernet (10BaseT) interface for remote LAN configuration and monitoring which allows the user to monitor and configure the equipment over a TCP-IP network from anywhere in the world. Orion Telecom Networks Inc. - 2006 Slide 2 T1 Voice Echo Canceller - 3U (10 per Chassis) Product Overview • • The echo canceller equipment offers fault recovery feature. It offers automatic by-pass upon power-supply failure / removal power supply. (i.e. it offers T1 circuit by-pass in the event of power supply failure). T1 echo canceller signaling protocols supported: – 24B (24 Voice Channels) with out-of-band signaling. – C7 / SS7 Signaling on any user selected time-slot. – 23B+D,PRI ISDN (23 Voice Channels+D Signaling Channel). – Robbed Bit Signaling. – All signaling options are USER SELECTABLE / USER CONFIGURABLE. Types of Echo canceller offered User Selectable: • 128ms -uni-directional (cancels the echo with upto 128ms tail at the far end). • 64ms - bi-directional (cancels the echo with upto 64ms tail in both directions). Orion Telecom Networks Inc. - 2006 Slide 3 T1 Voice Echo Canceller - 3U (10 per Chassis) Applications Datacomm Applications: Voice Over Frame Relay, Voice Over ATM, Voice Over Internet/LAN (VoIP). Central Office and PBX Applications: Network Trunks, Echo Canceller Pool, Common Equipment, Audio Conferencing Bridges. Voice Over ATM Applications: A multi-channel echo canceller resource or pool is shared among many channels to reduce cost, Echo cancellation is done at a DS0 level. Satellite Communications Applications: Digital Circuit Multiplication Equipment (DCME). Wireless Applications: Digital Cordless and Cellular Basestations, GSM, CDMA, Access Controllers. Voice Over Frame Relay, ATM Applications: Frame Relay and ATM routers and switches introduce large, variable, and unpredictable delays, Echoes from the Public Switched Telephone Network (PSTN) in combination with the delays from Frame Relay and ATM. Equipment yield objectionable speech quality.

Provides the user the flexibility to adjust and optimize the voice and transmit receive levels • Carrier-grade voice quality per AT&T Voice Quality Assessment Lab. • Ideally suited to handle most echo situations. • Assures operability with V.32 / V.32bis / V.34 modem and fax transmissions. Conforms to standards assuring proper public network operation andfacilitating system integration Orion Telecom Networks Inc. - 2006 Slide 5 T1 Voice Echo Canceller - 3U (10 per Chassis) Features & Highlights Removes residual echo and minimizes switching effects thereby providing high perceived speech quality Ensure echo canceller maintains excellent performance at all times in the presence of non-echo voice signals. Useful for trunks that have very low echoreturns loss. Ensure echo canceller maintains excellent performance at all times in presence of tones or signals including DTMF tones. Instability detector suppresses variable pitched ringing or oscillation. T1 Circuit by pass on power failure. Path change detect permits fast re-convergence when a major change occurs in the echo channel.
