Engage Delivers SuperTube T1/E1 Circuit to IP Packet Converter With VLAN/QOS Ethernet Switch.Engage SuperTube Reduces Conversion Overhead and Packet Processing by 75% for Both Wired and Wireless IP Backhaul Installations APTOS, Calif. -- Engage Communication, a leader in T1/E1 circuit to packet conversion and backhaul is shipping the IPTube G4. The Engage IPTube G4 T1 and IPTube G4 E1 are next generation cost and sized reduced solutions that reflect Engage's 8 years of Circuit Extension over Packet expertise. The IPTube G4 is available with one to four T1/E1 interfaces and a 10/100 BaseT Full/Half Duplex Ethernet Interface. An optional integrated 5 port QOS/VLAN/Rate Limiting Layer-2 Ethernet switch is available. The G4 is perfect for Cellular Base Station Backhaul, PBX (Private Branch eXchange) An inhouse telephone switching system that interconnects telephone extensions to each other as well as to the outside telephone network (PSTN). trunk conversion, for communication network installations such as public safety, transport or other government private networks, and for adaptation of Metro-Ethernet networks to interface to existing TDM (Time Division Multiplexing) A technology that transmits multiple signals simultaneously over a single transmission path. Each lower-speed signal is time sliced into one high-speed transmission. connections. The G4 transparently supports all signaling options including: PRI PRI: see Institutional Revolutionary party. (Primary Rate Interface) An ISDN service that provides 23 64 Kbps B (Bearer) channels and one 64 Kbps D (Data) channel (23B+D), which is equivalent to the 24 channels of a T1 line. ISDN ISDN in full Integrated Services Digital Network Digital telecommunications network that operates over standard copper telephone wires or other media. , SS7, ESF (1) (Extended SuperFrame) An enhanced T1 format that allows a line to be monitored during normal operation. It uses 24 frames grouped together (instead of the 12-frame D4 superframe) and provides room for CRC bits and other diagnostic commands. , SLC-96, CCIS (Common Channel Interoffice Signaling) The signaling technique used in the public switched telephone network that transmits voice conversations and control signals over separate networks. , proprietary out of band and robbed bit signaling A signaling method in a T1 circuit that uses bits from each of the 24 DS-0 channels. When channels carry switched voice traffic, each channel bank must be able to alert the other when a call is being placed on that channel. . The G4 is remotely manageable either via secure Telnet or SNMP (Simple Network Management Protocol) A widely used network monitoring and control protocol. Data are passed from SNMP agents, which are hardware and/or software processes reporting activity in each network device (hub, router, bridge, etc. . Secure Socket Shell (SSH (Secure SHell) A security protocol for logging into a remote server. SSH provides an encrypted session for transferring files and executing server programs. Also serving as a secure client/server connection for applications such as database access and e-mail, SSH supports a ) delivers encrypted communications between SSH clients and the Management interface. 5 port Ethernet switch is an option available on the G4 that can provide Ethernet QOS with up to 4 priority queues. The VLAN/QOS Ethernet switch functionality is a major plus to mobile operators as they move to upgrade their existing circuits to 3G and 4G services. A rate limiting capability built into the switch means that WAN bandwidth can be reserved for the T1/E1 interface real time circuit extension. The small foot print, low power and low cost and integrated Ethernet Switch make the G4 an exceptional choice for embedded solutions, tower and pole mount or transportable applications. The G4 enclosure measures 5.5" X 7" X 1.5" (1U Rack). SuperTube Option The SuperTube option combines four T1/E1 circuits into one IP packet stream. The SuperTube is specifically designed to facilitate the transport of multiple T1/E1 Circuits over packet connections with limited packet processing capabilities such as Wireless Ethernet. "The typical way to extend E1 circuits across packet networks is for each E1 to be encapsulated into individual IP packet streams," said Mark Doyle Engage President. "The SuperTube Sized IPTube reduces the encapsulation overhead bandwidth and the packet frequency by 75%." www.engageinc.com/Products2/iptube_G4_T1.htm www.engageinc.com/Products2/iptube_G4_E1.htm Engage Communication, www.engageinc.com, founded in 1989, has products to convert circuits to packets, encrypt both TDM and IP connections, convert encryptors to serial interfaces, transport SS7 over IP, route, bridge, and auto protect Voice/Video/Data Networks. The goal for Engage is to allow their customers to take advantage of the lower costs and flexibility associated with Packet transport while preserving investment in Circuit based premises equipment including: PBXs, Mobile services, Phone Switches, Voice and Data Multiplexors, Video and Audio Codecs, and Encryptors... |
