y Uses industry standard 16PAM line format.
y A pair of Loop-H3300 can be configured as DTE at one end and E1/T1 at the other in a bridge application.
y Each rack card has 12 LEDs for status, console port for terminal operation.
y Optional front panel keys and 2-line by 16-character display.
y Each unit can be set to be either master or slave. y Standard compliance for G.SHDSL, G.991-2, G.994-1
The Loop-H3300 provides high speed digital transport over twisted copper pairs using 16PAM 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 standalone 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/T1 with DTE interface at one end and E1/T1 at the other, as shown in the application illustrations.
From the shared common controller card of the rack cage, Loop-H supports configuration and diagnostics using keypads and LCD display on the front panel, or from a local or remote terminal. This enables users to execute inservice diagnostics and fault isolation.
