Data Sheet

TDM PSEUDOWIRE

LA-210 provides E1 or serial data (V.35,

X.21) connectivity over SHDSL using PWE

technology that supports MPLS and UDP/IP

encapsulation.

The following TDM emulation methods are

supported:

• CESoPSN per RFC 5086

• SAToP per RFC 4553.

LA-210 uses high-performance ASIC-based

buffering and forwarding techniques to

minimize end-to-end processing delay.

TIMING AND SYNCHRONIZATION

LA-210 supports the following in order to

synchronize TDM devices:

• NTR (network timing reference) –The

clock is transmitted over SHDSL lines

and recovered by LA-210

• ACR (adaptive clock recovery) – The

clock is recovered automatically from

incoming Ethernet frames (per G.823

and G.824, traffic interface with

100 ppb clock accuracy)

• DCR (differential clock recovery) – The

clock is recovered from real-time

transport protocol (RTP) timestamps in

the transmitted packets. This method

requires common reference clock at

both server and client sides, and

improves the recovered clock

performance. DCR mode allows use of

a TDM clock that is different from the

common clock for leased line

applications.

MANAGEMENT AND SECURITY

The unit can be managed using the

following ports and applications:

• Remote inband management via the

network ports using Telnet or

RADview, RAD’s SNMP-based

management system

• Out-of-band management via one of

the user ports configured as a

management port

• Local management via an ASCII

terminal.

Management traffic can be separated

from user traffic by creating dedicated

flows for management.

Databases and scripts of commonly used

commands can be easily created and

applied to multiple units using RAD’s

command line interface.

LA-210 ensures client-server

communication security and correct user

authentication using the following

protocols:

• SNMPv3

• RADIUS (client authentication only)

• SSH for Secure Shell communication

session

• Password-protected Telnet and local

terminal access.

MONITORING AND DIAGNOSTICS

Connectivity Tests

Ping test – Checking IP connectivity by

pinging an IP address

Trace route – Tracing the route and hops

from LA-210 to an IP address.

Loopback Tests

Layer-2 loopback testing with MAC

address swapping, in Flow mode. In this

scenario, LA-210 exchanges source and

destination MAC addresses of the

incoming packets. This type of loopback is

performed per flow and does not disrupt

traffic flows that are not being tested.

External and internal loopbacks can be

used to check TDM link connectivity.

BER Tests

Continuous connectivity check by inserting

errors in pre-defined time increments,

supported for E1 and PCS interfaces.
