Loop-H3900R Multi Rate xDSL Data Transport

Features:
  • Multi Rate xDSL Data Transport
  • DTE speed of n x 64 Kbps, n=1 to max n, where   max n= 4, 6, 8, 12, 18, 24, 32 for 1 line,   and n= 8, 12, 16, 24, 32 for 2 lines
  • DTE interface (V.35, EIA530, X.21, RS449), E1 interface,   or T1 interface
  • Distances vary by line speeds available depending on max n
  • Uses industry standard 2B1Q line format
  • A pair of Loop-H 3900 can be configured as DTE at one end   and E1 or T1 at the other
  • Each rack card has 12 LEDs for status
  • Each rack card share a controller card with front panel keys and 2-line by 40-character LCD display,
    with optional Ethernet,
    SNMP, and Telnet.

Description

Loop-H3900 provides high speed digital transport over twisted copper pairs using 2B1Q technology. Versatility of this series comes from a choice of digital interfaces and a choice of data rates, with the lower data rates applicable to longer reaches. Repeaters are available for extending the reach beyond a single span. This rack version is for central office use, while a stand-alone version is intended for customer premises installation. Either version, installed in pairs, can provide (a) an E1 link, with E1 interfaces, (b) a high speed data link with DTE interfaces, or (c) a data access to E1 with DTE interface at one end and E1 at the other, as shown in the application illustrations.
