Leased Line
Cost Elimination
Convert Voice Circuits to Ethernet
For many years, leased lines have been essential for supporting communications in SCADA systems, radio, and telephone services. However, a growing number of companies in sectors like utilities, public safety, military, and government are transitioning away from leased lines. They are opting for modern networks that facilitate seamless integration with legacy devices, provide vital redundancy and reliability, and deliver substantial cost savings to meet budget constraints.
Common Transition Solutions
T1 Circuit Extension Over IP
The IP•Tube GT1's 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. Transparent support for Modem, Fax, or Data circuits. Voice quality is not compromised.
T1 Multiplexor
The T1 MUX E&M employs high resolution Analog to Digital circuitry that maintains the quality of the original audio signal. The PCM CODEC converts 600 Ohm Analog Voice Band into Pulse Code Modulated m-Law G.711.
Extend CapEx Investments in Existing PBXs
Engage’s Circuit Emulation solutions benefits the balance sheet by extending the life of existing highly reliable and proven Private Branch Exchanges (PBXs).
The IP•Tube T1/E1 transparently supports all existing PBX functionality and features.
Far End Echo Cancelling
Packet networks that are not based upon simple point to point fiber connections typically introduce delay which causes echo.
Engage IP•Tube has models that utilizes a Digital Signal Processor that detects and cancels echo at the far end so that the packet network delay has no impact on echo.
Converting DS3 T3 E3 to Ethernet has a 10x ROI
Leasing DS3 T3 E3 circuits from carriers can cost tens of thousands of dollars per year. 50 megabit Ethernet connections from service providers are available for substanitially less.
Additionally if interfacility WANs have sufficient bandwidth there is no monthly leased line bill. Engage's IP•Tube DS3/T3/E3 is proving itself to be a cash cow with major organizations that require full-on 24/7/365 performance.
By routing T1 E1 DS3 T3 E3 circuits over Ethernet Packet networks organizations save OpEx and CapEx
Businesses incur significant recurring monthly costs for rigid-bandwidth leased lines used purely for the interconnection of PBXs and telecom switches. Toll charges assessed by long distance and local carriers are eliminated by transporting telecom traffic across the enterprise intranet, LAN, MAN, or WAN.
Ubiquity of IP
The ever-growing infrastructure of IP data oriented networks provides an economic opportunity for carrying the legacy circuit traffic. There can be multiple technology alternatives for transporting the voice traffic. The networks could utilize wireless (either licensed or unlicensed), private Ethernet, Metro-Ethernet, DSL, Cable, and WiMax. In the cable industry alone, cable modem technology has brought broadband Internet connectivity and additional packet services to a significant number of commercial customers. Employing this data connectivity to carry the more traditional digital voice trunks is a cost saving necessity for many existing private line customers.
In all cases, replacing the legacy switched circuit voice (and fax and PBX trunks) connections requires a robust technical solution. Adapting voice TDM to a packet network only to lose quality of service and expected service levels will not be tolerated. The equipment used to interface between the legacy connections and the new packet-based transport network must be easily installed, cost effective, secure and offer high standards of voice quality.
