Integrated platform for T1/E1 transport over SONET/SDH networks

5 September 2007 Telecoms, Datacoms, Wireless, IoT

Exar has developed a modular reference design platform, designated Orion, which delivers T1/E1 to SONET/SDH data transmission capabilities for metropolitan access networks. It is optimised for applications such as add-drop multiplexers, multiservice provisioning platforms, optical and wireless transport and routers.

Orion is a modular shelf that consists of several Exar devices: XRT86SH328 (Voyager), an integrated 28-channel T1/E1 LIU/Framer with VT/TU Mapper and M13 Multiplexer; XRT86SH221 (Voyager-lite), an integrated 21-channel E1 LIU/Framer with VT/TU Mapper; and the XRT91L30, a single channel OC-3/OC-12 transceiver.

The platform's flexible system architecture enables the same shelf hardware to be used for either 84 T1s or 63 E1s aggregated into OC-3/STM-1, simply by interchanging the module that consists of three XRT86SH328s or three XRT86SH221s. The design platform offers a high density solution converting T/E channels into VT1.5 or VT2 tributaries and directly mapping them into SONET/SDH STS3/STM1 data rate. The design uses a common telecom bus operating at 19,44 MHz. For optical transmission, the STS3/STM1 telecom bus interface is coupled with Exar's XRT91L30 OC-12/OC-3 transceiver and an optical module.

In addition to the shelf hardware, the reference design platform also includes hardware schematics, PCB layout guidelines, user guide, GUI and software API documents. The device drivers and GUI required to support the Orion system on specific network configurations can be customised for specific customer applications.
