Telco Systems Introduces T-Marc Ethernet Demarcation/Service Termination Devices

Telco Systems, a provider of carrier-class transport and access solutions for public and private IP and TDM networks, today introduced the first two models of its new T-Marc product line, a family of cost-effective and compact Ethernet demarcation and service delivery customer located devices.

T-Marc enables TDM- and packet-based carriers to reduce opex and capex for carrier-grade Ethernet and TDM-over-Ethernet services. It provides an extensive operation, administration and maintenance (OAM) toolkit along with QoS mechanisms, which enables carriers to minimize service calls and meet their SLAs.

"The T-Marc next-generation solutions enable service providers to use Ethernet all-the-way, while mixing and matching legacy and new services on a common infrastructure with the ability to remotely monitor, test and manage their services, without the need for truck rolls," says Dave Lee, vice president of marketing and services for Telco Systems. "It also meets service providers' requirements for multiservice, multi-application, multisite and multicarrier SLA enforcement while providing the lowest latency of any circuit emulation service (CES) pseudowire demarc device available today, which is particularly critical for cable providers," Lee adds.

One of the main objectives of a demarcation device is network and infrastructure diagnostics. T-Marc accomplishes this with its extensive OAM toolkit, complying with IEEE 802.3ah Ethernet First Mile Task Force and Metro Ethernet Forum, IEEE 802.1ag OAM standards. It provides a variety of test functions for infrastructure integrity testing, remote loop-back testing, fault propagation and isolation, and performance and provisioning monitoring across the entire network, including latency, loss, jitter and trace route measurements.

The T-Marc delivers fast Ethernet, gigabit Ethernet and T1/E1 services over Ethernet using CES Pseudowire. It also provides performance and SLA control and monitoring to support VoIP, TDM voice, video and data services.

"The T-Marc was developed to provide service providers, be they cable, TDM, packet-based or wireless, with an extremely cost-effective solution for the delivery of carrier-grade Ethernet and legacy T1/E1 services, to the edge on one converged network," says Lee.

The T-Marc can be used on its own or in conjunction with Telco Systems' new carrier-class T-Metro, an MPLS/HVPLS-based multiservice metro Ethernet access platform, or its T5 Compact family of Ethernet aggregation switches, all of which provide sub 50ms protection switching. When used with Telco Systems' T-Metro, service providers can extend control and scalability of their MPLS core out to the network edge, while providing T1/E1 services with extensive remote diagnostics capabilities.

The T-Marc family delivers extensive Layer 2 capabilities as well as enhanced features including access control lists, advanced QoS support, traffic shaping and rate limiting. The T-Marc-254 delivers 4 T1/E1 CES ports. Both T-Marc 250 and T-Marc 254 have 4 10/100BaseT ports; 1 100/1000BaseX port; and 1 universal port (1000BaseX, 100BaseFX or 10/100/1000BaseT).

Key applications and services for the T-Marc include enterprise, multitenant/multidwelling units (MTU/MDU); as a copper or fiber Ethernet-based demarcation point; services extension node; high-performance private E-LAN and E-Line; Ethernet VPN and Transparent LAN Service (TLS); access platform OAM extension; industrial parks for FTTx and EFM; metro Ethernet; multiservice, multicarrier; TDM/cellular backhaul; T1/E1 leased line replacement; PBX-to-PSTN backhaul and PBX-to-PBX (tie-line) connectivity;Ethernet switching and routing; and Internet access.
