TranSwitch® Corporation (NASDAQ: TXCC), a leading provider of high-speed semiconductor solutions for voice, data and video communications, today announced that Loop Telecom will be utilizing TranSwitch’s EtherMap®-PDH devices in their next generation access platform to enable Ethernet over Plesiochronous Digital Hierarchy (PDH) infrastructure.
“Ethernet over Synchronous Optical Network / Synchronous Digital Hierarchy (EoS) is the preferred mode for carriers to transport Ethernet services over their existing optical networks. Yet, the vast majority of small and medium businesses who could benefit from such services cannot gain access to them because they are connected to the network over the existing copper PDH infrastructure. Our EtherMap-PDH product was designed to address this gap by enabling efficient and reliable transport of Ethernet over PDH (EoPDH). The Loop-IP6416 IP Inverse Multiplexer / Media Converter is an excellent example of the innovative EoPDH platforms that will enable carriers to leverage their existing copper infrastructure to provide Ethernet based data services on a ubiquitous basis.” stated Radu Iorgulescu, Director of Product Management for TranSwitch.
The Loop-IP6416 IP Inverse Multiplexer / Media Converter allows Service Providers to offer Ethernet services over any existing copper, optical or microwave infrastructure carrying E1 or T1 circuits. Up to 16 E1 or T1 circuits can be concatenated to form a single channel over which the Ethernet traffic is carried, thus providing customers up to 32 Mb/s of network bandwidth.
The Loop-IP6416 can be provisioned with up to 16 E1/T1 ports. Each port has automatic E1/T1 channel failure detection capability and is equipped with a status indicator LED. The number of E1/T1 channels transporting Ethernet traffic can be re-assigned either in response to a network failure on one or more channels or through operator initiated commands. The unit is equipped with a console port, which allows users to execute in-service diagnostics and fault isolation from a local or remote terminal and also supports remote site connection to Telnet via the Ethernet port. The Loop-IP6416 supports several power options including dual DC, front/back AC and hybrid AC/DC.
The TranSwitch EtherMap-PDH is based on the latest ITU-T Standards G.8040, G.7043 and G.7042 for Generic Framing Procedure (GFP), Virtual Concatenation (VCAT) and Link Capacity Adjustment Scheme (LCAS) respectively. These new standards effectively enable the same framing, concatenation and capacity management schemes incorporated in TranSwitch’s highly successful EoS product family to be extended for PDH network applications.
GFP/VCAT and LCAS were developed to provide lower network latency and faster network restoration in case of individual circuit failure compared to other schemes used prior to these standards. EtherMap-PDH incorporates several innovative features such as GFP packet header correction and LCAS hitless restoration in order to provide highly reliable and efficient packet transport, resulting in fewer dropped packets and greater overall throughput.
“The support of PPP/HDLC and the field-proven LCAS functionality in the EtherMap-PDH device was critical for our Loop IP6416 platform. For example, the Loop IP6416 supports the automatic E1/T1 channel failure detection feature in which if one of the E1s failed, the remaining bandwidth of 15 E1s would seamlessly adjust to sustain the traffic, this would result in a minimal loss of traffic”, said Joe Lau, Vice President of Loop Telecom. “Furthermore, the ability to provide built-in test pattern and remote E1 loopback functionality while in the VCAT-mode is of tremendous value to a Service Provider, especially during the System Line-up and Test (SLAT) of the service”, continued Joe Lau.
“The merits of GFP/VCAT and LCAS are being recognized by telecom operators worldwide, as seen by recent Request for Proposal (RFP) activity. We have seen continued EtherMap-PDH deployment by the OEMs globally for both wireline and wireless applications”, stated Radu Iorgulescu.
Using the EtherMap-PDH device, OEMs can extend the life-span of their existing platform by developing a universal PDH Service Card while reusing the backplane and chassis. The PDH interfaces (E1/T1/J1 and DS3) can work in independent or protected mode, making it suitable for a variety of applications that include wireless base stations, Ethernet switch/routers and MSPP platforms.
