RAD Data Communications 2011 Catalog

•

Transparent modem concentrator

•

Operates 16 SHDSL, E1 modems on

2-wire

•

Multiple data rates: between 64 kbps

and 2,048 kbps

•

ITU-T standards: G.703, G.704

•

Compact unit

using a dedicated management port, while

maintaining separation between management and

user traffic via the use of VLANs. Advanced FCAPS

(Fault, Configuration, Administration, Performance,

Security) and diagnostic tools are provided by

RADview-EMS, RAD’s carrier-class element

management system, via an SNMP-based GUI. The

LRS-16 also supports a variety of access protocols,

including SNMP, Web server, and Telnet.

LRS-16 is supplied in a 1U-high 19-inch enclosure.

The LRS-16 is a managed SHDSL modem

concentrator presenting a cost-effective central-

site solution for point-to-point extension of E1

services in the Local Loop.

The concentrator can operate opposite 16

ASMi-52 SHDSL modems at remote locations,

providing E1 services over 2-wire lines. Each

one of the 16 fixed ports inside the LRS-16 can

have its own separate clocking.

Extended range

LRS-16 employs standard SHDSL TC-PAM 16

technology to extend the transmission range,

thus enabling carriers to reach more customers

at lower costs. The device uses an embedded

operation channel (EOC) for controlling and

monitoring the remote unit. The management

channel uses SHDSL overhead bits in compliance

with ITU-T G.991.2 requirements, and operates

without interfering with the data transmission.

Power supplies

LRS-16 operates with single or dual power

supplies. A power supply can be hot-swapped

(replaced) during operation, without affecting

system performance.

Management

The LRS-16 features flexible management

capabilities, including local management via an

ASCII terminal (RS-232). In addition, remote

management can be performed either inband

using the network or user ports or out-of-band

ASM-MN-214

Chassis for Short Range Modems

The ASM-MN-214 versatile modem rack is a

high density unit capable of housing any

combination of up to 14 cards.

The ASM-MN-214 accommodates two separate

power supplies. Each power supply supports a

full rack of any combination of cards. The power

supplies can be either AC or DC and are suitable

for power redundancy. Replacement during

operation (hot-swapping) is possible, with no

effect on the modems and their data

transmission.

Cards that are currently supported: ASM-10/8/R,

ASM-31/R, ASM-40-1/R, FOM-20/R, FOM-40/R,

FOM-E1T1/R, FCD-2L/R, RIC-E1/R, RIC-T1/R.

The ASM-MN-214 has a terminal block for the

line interface and a 25-pin connector for the

digital interface. The terminal block is a snap-

type connector for easy replacement.

An optional mechanical adapter, the CIA, is used

to convert the 25-pin connector to the required

physical connector for either V.35 or X.21

interfaces.
