Encrypted T1 Over IP
Black•Tube for T1 Circuit Extension over IP
The Black•Tube transparent operation maintains the proprietary signaling required to support PBX features such as call conferencing, call forwarding, caller ID and SS7. Legacy phone equipment investment is preserved. Available with Integrated Echo Cancellation and Lossless Data Compression.
Echo Cancellation -ECAN
Black•Tube's Echo Cancellation provides the elasticity to support Echo Free Voice connections across networks with packet jitter.
Echo Cancellor is DSP based and cancels up to 64 milliseconds of Far End echo. The echo canceller meets ITU-T G.164, G.165 and ITU-T G.168 requirements.
|Lossless Data Compression|
Lossless Data Compression continuously detects idle/redundant data within each T1 Voice circuit resulting in as much as a 40 to 1 bandwidth savings. The compression works from the lowest latency setting of 8 T1 frames to the highest setting of 40 T1 frames per packet.
|LAN Protector -PRO|
The Protector option provides for automatic protection of the T1 circuit over independent IP packet routes. After conversion of the T1 circuit into IP packets, two identical packet streams are created. These duplicate packet streams are used to provide redundant IP connectivity to the remote location in either “Always-On” or “On-Demand” switch over modes.
The need to Protect Critical Communications is in high demand for the following applications:
•Public Safety Network Redundancy for Police, Fire and Medical
|Link Protector -LPT|
The T1 Link Protector provides an automatic back up for T1 circuits with T1 Over IP connecting via Wireless Ethernet, Gigabit Ethernet, IP Satellite Services, xDSL,....
• Automatic Protection Switch for T1 Circuit
|Alternator option alternatively sends the IP packetized T1 frames on LAN 1 and LAN 2. The Alternator option enables fractional and full T1 circuits to be split over two IP WAN connections such as SDSL.|
