RT, and connected to the Client end facility (G.SHDSL modem)
via 2-wire copper lines. The GSH Module provides three types of
Digital Leased Line Interfaces:

(1) ITU-T G.703 E1 Interface

(2) ITU-T V.35 Interface

(3) 10/100 Base-TX Ethernet Interface

E1 Interface

Complies with ITU-T G.703/G.704/G.706.

Please refer to Chapter 11 of this Manual for information on
technological details and interface parameters.

V.35 Interface

Supports N 64 Kbit/s subscriber data frequency. N=1~31.

Ethernet Interface

„ Provides 10Base-T and 100Base-TX Auto-Negotiation

Interfaces.

„ Complies with IEEE 802.3 Ethernet and IEEE 802.3u Fast

Ethernet standard regulations, and supports Full Duplex and
Half Duplex transmission. With Cat-5 UTP 10 copper cables,
its transmission distance can reach up to 100 meters.

„ Provides Rate Limiting functions for receiving and transmitting

data. The frequency range can be set to anywhere from 192
Kbit/s to 2048 Kbit/s (adjusted at 64 Kbit/s per step). The
final error rate is less than 10%.
