•

Ethernet link and pseudowire

redundancy

communications. In addition, it supports cellular

operators in migrating their services to

economical packet switched backhaul.

IPmux-216's high port count makes it ideal for

central POPs as well as for transport providers

serving several mobile operators from shared

towers.

Advanced pseudowire functionality

Incorporating RAD’s new generation of ASIC

processors, the IPmux-216 features enhanced

pseudowire performance with minimal

processing delay, including support for all

standard TDM circuit emulation modes, such as

TDMoIP, CESoPSN, SAToP, HDLCoPSN, and

CESoEth (MEF-8). Featuring a 256-circuit

pseudowire capacity, the IPmux-216 enables

each timeslot to be assigned a separately

configured pseudowire connection, thereby

supporting multiple PW flavors simultaneously.

By grooming DS0-level bundles, the IPmux-216

also facilitates an efficient use of the expensive

TDM ports.

Clock recovery and timing

The IPmux-216 ensures end-to-end timing

accuracy for real-time services across non-

deterministic packet networks. Featuring

adaptive clock recovery (ACR) capabilities, a

remote IPmux-216 can accurately regenerate an

original clock transmission in varying network

load conditions. The IPmux-216 conforms to

ITU-T G.823/G.824 traffic and synchronization

interface requirements and to G.8261-defined

scenarios, providing low latency, attenuating

delay variations and enabling service resiliency.

Such high precision clocking attributes provide a

frequency accuracy level of 16 ppb,

guaranteeing smooth operation of 2G and 3G

cellular equipment over PSNs.

Ethernet QoS and VLAN capabilities

The IPmux-216 includes an internal Ethernet

bridge, operating in either VLAN-aware or VLAN-

unaware mode. VLAN stacking allows traffic

separation between different users or services.

Supporting Ethernet private line (EPL) service

provisioning, the IPmux-216 also includes

enhanced traffic engineering and CIR/CBS rate

limitation features, thereby enabling service

providers to granularly adjust bandwidth to fit

capacity requirements. SLA enforcement and

QoS guarantees are supported by four strict

priority queues, classified by VLAN tags, per port

802.1p bits, IP Precedence, or ToS/DSCP bits.

OAM and diagnostics

The IPmux-216 incorporates a pseudowire OAM

mechanism that enables end-to-end monitoring

of the pseudowire link, performing connectivity

verification and round-trip delay measurements,

as well as preventing pseudowire configuration

errors. Diagnostic loopbacks can be remotely

activated, while network condition statistics for

the LAN and IP layers are also monitored and

stored by the device. Performance monitoring

parameters include packet loss, packet mismatch

and packet delay variation.

Service center management and security

The IPmux-216 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), service

provisioning and diagnostic tools are provided

by RADview-SC/TDMoIP, RAD’s network

management system, via an SNMP-based GUI.

The IPmux-216 also supports a variety of

configuration access channels, including Telnet,

SNMP, Web server, and TFTP. Incorporated

security features include Secure Shell (SSH),

Web-based Secure Socket Layer (SSL), SNMPv3,

and RADIUS.

The IPmux-216 TDM pseudowire access gateway

transparently delivers framed or unframed E1 or

T1 signals, HDLC-based data streams and user LAN

traffic over packet switched networks, via copper

or fiber Fast Ethernet or Gigabit Ethernet uplinks.

The IPmux-216’s compact design, ease of

installation and advanced traffic management

capabilities enable carriers to extend their services

from legacy backbones over greenfield packet

networks, without affecting customer experience

or replacing existing end-user equipment. It also

allows service providers to add traditional leased

line services to their Layer 2 portfolio and permits

enterprises to reduce their IT expenses on PSTN

connectivity and branch-to-branch
