Loop-H3900 SERIES MULTI RATE 
Description This stand-alone version is intended for customer premises
y DTE speed of n x 64 Kbps, n=1 to max n, where max n= 4, 6, 8, 12, 24, 32 for 1 line, and n= 8, 12, 16, 24, 32 for 2 lines.
y Distances vary by line speeds, wire thickness and environmental factors, depending on max n. y DTE interface (V.35, EIA530, X.21, RS449), E1 interface, or Router interface. y Integral Router. y Uses industry standard 2B1Q line format. y A pair of Loop-H 3900 can be configured as DTE at one end and E1 at the other in a bridge application. 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 Multi-color LED indicators. y Compatible with Loop-H 3900 rack version. y Standard compliance: For E1-HSDL, ETSI RTR/TM-03036 and ETSI TS 101 135 (formerly ETR 152).
Iinstallation while the rack version is for central office use. 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. The Loop-H also supports an integral router. This router can be connected directly to a LAN for transport of information out to the network, avoiding the cost and space of an external router.The Loop-H supports configuration and diagnostics using keypads and LCD display on the front panel, or from a local or remote terminal. This execution of in-service diagnostics and fault isolation.
