ASMi-52

Features

• Dedicated G.SHDSL modem with remote management
• Operates over 2-wire and 4-wire lines, enabling service over any copper infrastructure
• Utilizes TC-PAM line coding for extending the operation range to 12.0 km (7.4 miles) and eliminating the need for repeaters
• Operates at multiple data rates between 64 kbps and 2048 kbps enabling single-platform system upgrades
• Supports X.21, V.35, G.703/G.704 E1 and Ethernet interfaces, allowing connection to different DTE types
• Supports embedded operation channel for end-to-end system management and supervision as per ITU-T G.991.2
• Provides extensive diagnostics, including loopbacks, G.SHDSL and E1 performance monitoring

Description

• 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.
