Ideal connectivity for business services and mobile backhaul

Deploying contemporary Ethernet-centric services from a service provider’s embedded base of access equipment is challenging enough, but the fact is that modernizing a traditional digital loop carrier system to support fiber-based and Ethernet connectivity, without cannibalizing existing revenue from copper-based legacy services, is nearly impossible.  What service providers need is a fiber-fed digital loop carrier system that supports a wide variety of service, transport and network connectivity, including copper, optical, Ethernet, SONET and even ATM.

Tellabs Broadband products support Ethernet transport and service end-to-end, including Ethernet to the core, Ethernet within the system and Ethernet service drops. The product portfolio includes Gigabit Ethernet interfaces toward the core network, across interterminal transport and 10/100 Ethernet, and drops to end users. The transport interfaces are ideal for high-capacity applications or for use in interfacing with embedded Ethernet equipment. Tellabs’ 10/100 Ethernet interfaces provide ideal support for business customers and mobile backhaul. The Tellabs 1000 MSAP can support these Ethernet interfaces simultaneously as it supports legacy services, like ISDN, FAX, DID/DOD, 2-Wire/4-Wire, Pay Phone, E&M, TO and EBS. Thus, the Tellabs 1000 MSAP is unique in that it can support these next-generation IP/Ethernet initiatives without sacrificing traditional TDM revenue sources.

Quick Facts


  • Flexible Ethernet transport between central office, remote cabinet or customer premises.


  • High availability with card and port level redundancy options.


  • End-to-end Ethernet implementations can be configured with both Ethernet service and transport cards.



  • Simultaneous support of Ethernet, ATM, SONET and TDM circuits within the same system.


  • Following IEEE standards-based Ethernet technologies.


  • Multiple Small Form-factor Pluggable (SFP) available for both copper and fiber.


Ethernet connectivity choices


The Tellabs 1000 MSAP Ethernet Service 10/100 plug-in card (ES 10/100) can deliver Ethernet services to business premises, Multiple Dwelling Units (MDUs) and cell site base stations. The ES 10/100 is supported in the Tellabs 1000 MSAP and can be located in any of the multi-purpose shelf slots, while the Tellabs 1000 MSAP Gigabit Ethernet Transceiver (GbE222) is a high-bandwidth, cost-effective Gigabit Ethernet uplink and inter-terminal transport interface for the Tellabs 1000 MSAP. The GbE222 installs into the Tellabs 1000 MSAP to support voice transport (GR-303, GR-08, GR-57 and SIP), Ethernet traffic aggregation for High Speed Internet (HSI), IP Television (IPTV), business premises applications and cell site base station traffic backhaul too.


Flexible Ethernet transport


The Tellabs GbE222 plug-in card provides point-to-point inter-terminal transport between Central Office (CO) based Local Exchange Terminals (LET) and Remote Subscriber Terminals (RST) located in non-environmentally controlled cabinets or huts. It can also act as the Ethernet data and internet uplink to the Wider Area Network (WAN) edge or metro switch. The GbE222 provides two (2) Gigabit Ethernet ports equipped with optional configurations of 1000-Base-SX Small Form-factor Pluggable (SFP) and 1000-Base-LX SFP optics.


Highly-availability Ethernet


Redundancy is supported with the Tellabs 1000 GbE222 plug-in card and the implementation of Link Aggregation (IEEE 802.3ad LAG) at both card level and per port level. This provides resilient connectivity across central office, remote cabinets and customer premises.

End-to-end Ethernet


With the Ethernet Service 10/100 plug-in card (ES 10/100) used in conjunction with Gigabit Ethernet Transceiver (GbE222) card, in transport and network uplink configurations, the Tellabs 1000 MSAP can deliver end-to-end Ethernet interfaces. Even better, these Ethernet-based interfaces can be deployed without abandoning revenue-generating legacy Time Division Multiplexing (TDM) and Special Services that are delivered simultaneously from within the same Tellabs 1000 MSAP shelf.


Ethernet, ATM and TDM Interworking


Asynchronous Transfer Mode (ATM), TDM and Ethernet interworking is achieved with ATM-to-Ethernet Connection (AEC), Ethernet-to-Ethernet Connection (EEC) and Ethernet-to-ATM Connection (EAC) supported across the Tellabs 1000 MSAP system.


Standards-based Ethernet


Standards-based Ethernet is support with VLAN tagging per IEEE 802.1q, prioritization per IEEE 802.1p and Transparent LAN Services (TLS) when used with GbE222 plug-in card. Jumbo Ethernet frames  are supported up to 2,000 bytes Maximum Transmission Unit (MTU) and Service Level Agreements (SLA) can be established with Committed Information Rate (CIR) and Committed Burst Size (CBS).
