Crocus HS

• Synchronous high-speed baseband modem for 2-wire unconditioned, unshielded twisted-pair cables.
• Up to 9 km at 144 kbps over 0.5-mm cable without repeaters
  Powerful 2B1Q line-coding scheme
• User selectable data rates from 48 kbps to 144 kbps
• Central site high-density card-nests for up to 30 modems
• Modular plug-in DTE interfaces for maximum flexibility and efficient stock management

The Crocus High Speed (HS) is a new-generation manageable base band modem for digital subscriber lines or private copper networks. The modem offers multiple user speeds between 48 and 144 kbps for operation over a single unconditioned, unshielded twisted pair. Through a powerful 2B1Q line-coding scheme and adaptive line equalisation, the Crocus HS covers long distances without the need for expensive repeaters or pair selection.

A complete range of plug-in interface boards makes the Crocus HS ideal for interfacing with almost any application. Not only traditional serial interfaces such as V.24, V.35, V.36, RS-530 and X.21, but also G703 (64 kbps co-directional) and direct Ethernet 10BaseT connections with integrated bridge or router functionality are available. This entire range of interface boards can be exchanged in only a few seconds.

Crocus SHDSL

•  High-speed baseband modem for use on a single unshielded twisted copper pair
• Based on the new G.SHDSL standard for higher speeds and longer loop ranges
• Variable line-transmission rates up to 2.3 Mbps
• Advanced free maintenance software
• Manageable under HP OpenView®
• Central-site high-density cardnest solution for up to 30 modems
• Modular plug-in DTE interfaces for maximum flexibility and efficient stock management

The CROCUS SHDSL is a state-of-the-art baseband modem offering full duplex transmission up to 2.3 Mbps over a single two-wire unconditioned unshielded twisted-pair cable. The line speed of the modem can be adapted to optimise the throughput as a function of the characteristics of the local loop. The equipment is based on a new modulation technology called TC-PAM (Trellis Coded Pulse Amplitude Modulation), which guarantees higher speeds and longer loop performance. A complete range of plug-in interface boards makes the Crocus SHDSL ideal for interfacing with almost any application. Not only traditional serial interfaces such as V.35, V.36, RS-530 and X.21, but also G.703 and direct Ethernet 10BaseT connections with integrated bridge or routerfunctionality are available. All these interface boards can be exchanged in only a few seconds.
