4 Crocus SHDSL G703 Chapter 1 User manual Introducing the Crocus SHDSL G703 1.1 Crocus SHDSL G703 features The Crocus SHDSL G.703 (Symmetric High Bit Rate Digital Subscriber Line) is a manageable baseband modem offering full 2,3 Mbps duplex transmission over unconditioned unshielded twisted-pair cable. A dedicated 2-pair version offers the possibility to extend the reach to longer distances or higher speeds (up to 4.6 Mbps). For extreme long distances, the equipment can fall back to a lower transmission rate, offering reduced speeds on the Fractional E1 (FE1) operation. The equipment is based on the TC-PAM (Trellis Coded Pulse Amplitude Modulation) modulation, which guarantees higher speeds and longer loop performance. It also guarantees spectral compatibility with legacy and ADSL transmission systems in the same cable bundle. The unit can be used in a point-to-point configuration, or can be used with a central solution based on card-nest 4 (CN4) or the OneAccess 2300. The Crocus SHDSL G.703 is available as a locally or remotely powered (RP) unit. The remotely powered unit can also be locally powered at -48VDC directly or by 230Vac through an external power adapter. The unit is designed for integration into demanding network environments and can be controlled by the complete set of network maintenance and management tools.
