-
ASMi-52, G.SHDSL modem, operates in
full duplex mode over 2-wire and 4-wire lines.
-
ASMi-52 supports multiple data rates:
n x 64 kbps (n = 1, 2, ..., 32), or n x 128 kbps (n = 1, 2,
..., 16). The data rates depend on the line interface and
DTE interface types.
-
ASMi-52 employs standard G.SHDSL TC-PAM
technology to extend the transmission range (see Table 1 and
Table 2), enabling the carrier to reach more customers at
lower cost.
-
ASMi-52 supports X.21, V.35 and
G.703/G.704 E1 interfaces. In addition, the modem supports
Ethernet interface modules with a built-in bridge (IR-ETH/Q)
or an IP router (IR-IP), which allow LAN-to-LAN connectivity
using G.SHDSL technology.
-
The modem uses an Embedded Operation
Channel (EOC) for controlling and monitoring the remote
unit. The management channel uses G.SHDSL overhead bits,
operating without interfering with the data transmission in
compliance with the ITU-T G.991.2 requirements.
-
ASMi-52 is managed via an ASCII
terminal connected to the modem's supervisory port by an
embedded menu-driven software.
-
ASMi-52 has comprehensive diagnostics
capabilities that include the following test options:
-
Real-time alarms to alert user on
fault conditions
-
V.54 local analog and remote
digital loopbacks
-
G.SHDSL and E1 statistics
collection for 15-minute and day intervals.
-
The modem provides high voltage line
protection in compliance with ITU K.21 and UL1950.
