Advanced pseudowire functionality

Incorporating RAD’s new generation of ASIC

processors, the IPmux-2L features enhanced

pseudowire performance with minimal

processing delay, including support for all

standard TDM circuit emulation modes: TDMoIP,

CESoPSN, SAToP, and HDLCoPSN. Featuring a

63-circuit pseudowire capacity, the IPmux-2L

supports individually configured pseudowire

connections in timeslot granularity, thereby

supporting multiple PW types simultaneously. By

grooming DS0-level bundles, the IPmux-2L also

facilitates an efficient use of the TDM ports.

Configurable packet size balances PSN

throughput and delay while a jitter buffer

compensates for packet delay variation (jitter)

of up to 200 msec in the network.

Pseudowire timing

The IPmux-2L supports various clocking options

to ensure synchronization as any standard TDM

device. These include loopback timing, external

clock source or internal, using the device’s

internal oscillator.

The IPmux-2L can also recover the original clock

with great accuracy, using per-port adaptive

clock recovery. It complies with G.823 traffic

interface mask and provides frequency accuracy

of up to 100 ppb (parts per billion).

Ethernet capabilities

The IPmux-2L includes an Ethernet switch

featuring three Ethernet ports, whereby one

port serves as the network interface and the

other two are used for user traffic. Supported

Ethernet attributes include port-based VLAN

membership and VLAN tagging, as well as VLAN

stacking (Q-in-Q). In addition, it supports port-

based rate limitation, enabling the total

transmitted bandwidth to be adapted to the

limitations of the transport media.

Ethernet QoS features include four priority

queues, scheduled by Strict Priority or Weighted

Fair Queue (WFQ). Traffic is classified according

to IP Precedence, 802.1p, DSCP, or port default

priority.

Interfaces

The IPmux-2L features the following interfaces:

•

One or two E1 user ports

•

n x 64 kbps port with various interface

options: X.21, V.35, V.36/RS-449,

RS-530/RS-422, and V.24/RS-232

•

A single network Ethernet port, with an

optional 10/100BaseT or 100BaseFX interface

•

Two user Ethernet ports, both UTP-based, or

one copper and one fiber-based

EMS management

The IPmux-2L features flexible management

capabilities, including local management via an

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

management can be performed either inband or

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

while maintaining separation between

management and user traffic via the use of

VLANs. Advanced FCAPS (Fault, Configuration,

Accounting, Performance, Security) and

diagnostic tools are provided by RADview-EMS,

RAD’s carrier-class element management

system, via an SNMP-based GUI.

The IPmux-2L also supports a variety of

configuration access channels, including Telnet,

SNMP, Web server, and TFTP.

The IPmux-2L is a cost-competitive TDM

pseudowire access gateway, converging framed or

unframed E1 streams along with serial data and

user LAN traffic over IP, MPLS or Ethernet

networks. It offers an ideal solution for economical

PSTN access and TDM trunking over wired and

radio packet access. The IPmux-2L’s extensive TDM

pseudowire support enables enterprises and utility

companies to take advantage of new packet

switched networks for legacy services transport,

without replacing their existing equipment or

affecting service quality.
