IPmux-216

TDM Pseudowire Access Gateway• Comprehensive compliance with pseudowire/circuit emulation standards
including TDMoIP, CESoPSN, SAToP, CESoETH and HDLCoPSN• Industry-leading adaptive clock recovery mechanism suitable for cellular
backhaul over packet-based networks

TDM circuit emulation
over packet-switched
networks• Carrier-class/environmentally hardened device• Extensive OAM and performance monitoring capabilities• Three auto-detecting Gigabit or Fast Ethernet SFP- or UTP-based ports, and 8
or 16 TDM service ports

IPmux®-216 provides legacy services overpacket networks. The device converts thedata stream from its user E1/T1 ports into
packets for transmission over the
network. These packets are transmitted
via the IPmux-216 Ethernet network port
to the PSN. A remote pseudowire device
converts the packets back to their originalformat.

PSEUDOWIRE FUNCTIONALITY
The ASIC-based architecture provides arobust and high performance pseudowire
solution with minimal processing delay.

IPmux-216
TDM Pseudowire Access Gateway

The unit employs various pseudowire
encapsulation methods, including TDMoIP,
CESoPSN, SAToP, CESoETH (MEF 8) andHDLCoPSN.

PSEUDOWIRE TIMINGTDM INTERFACE

End-to-end synchronization between
circuits is maintained by deploying
advanced clock recovery mechanisms.

8 or 16 E1 or T1 ports provide
connectivity to any standard E1 or T1
device.

Proper balance between PSN throughput
and delay is achieved via configurable
packet size.

Clock recovery conforms to G.823 andG.824 traffic interface using
G.8261-defined scenarios.

The E1 and T1 interfaces feature:•

Integral LTU/CSU for long haul
applications

A jitter buffer compensates for packet
delay variation (jitter) of up to 180 msec
in the network.

Advanced clock recovery conforms toG.823 synchronization interface using
G.8261-defined scenarios and achieves
16 ppb clock accuracy.

•

G.703 and G.704 framing modes•

CAS and CRC-4 bit generation (E1)•

D4/SF and ESF framing (T1)•

Robbed bit (T1).

PSEUDOWIRE QoS/CoS
Ethernet networks – outgoing pseudowire
packets are assigned a dedicated VLAN ID
according to 802.1q and marked forpriority using 802.1P bits.
IP networks – outgoing pseudowire
packets are marked for priority using
DSCP, ToS, or Diffserv bits.

The system clock ensures a single clock
source for all TDM links. The system clock
uses master and fallback timing sources
for clock redundancy. IPmux-216 also
provides system clock input and output via
an external clock port.

MPLS networks – outgoing pseudowire
packets are assigned to a specific MPLS
tunnel and marked for priority using EXP
bits.

Figure 1. 2G/3G Cellular Backhaul

Data SheetETHERNET INTERFACE
The following Ethernet ports are available:•

One network port•

One network/user port•

One user port.

The Ethernet ports accept a wide range of
Gigabit and Fast Ethernet SFP-based fiber
optic and electric, as well as built-in UTP
interfaces.
ETHERNET CAPABILITIESIPmux-216 features an internal bridge,
operating in VLAN-aware and
VLAN-unaware modes.
VLAN stacking is used for traffic
separation between different users orservices, by defining a service provider
VLAN ID per customer or service. When
VLAN stacking is used, a service provider
VLAN tag is added to the user traffic andremoved from network traffic. Bothservice provider VLAN ID and service
provider VLAN priority can be defined.

IPmux-216 provides four priority queues
for each port or pseudowire traffic flow.
User traffic can be prioritized according to
VLAN priority, DSCP, IP Precedence or per
port.
Ingress and egress rate can be limited peruser and network port. Rate limitation is
configured per packet type.
ETHERNET RING TOPOLOGIESA G.8032 Layer-2 Ethernet ring is used by
IPmux-216 for traffic protection. This
technology builds a logical ring, defined asa set of IEEE 802.1-compliant bridges, andprotects against link and node failures. To
achieve this, every node in the ring has
two bridge ports connected to adjacentnodes. The ring itself is constructedindependently of the transport technology
used at the server layer. Failures in thering are detected by using Ethernet OAM(Y.1731) continuity check (CC) messages
between adjacent nodes.
In addition, the unit employs Resilient
Ethernet Ring technology to construct a
self-healing Ethernet fiber ring topology(ring resiliency is similar to that of
SDH/SONET networks). In case of link
failure on any segment of the ring, thepseudowire traffic is rerouted within
50 ms. A single ring supports up to
16 nodes.

Figure 2. Private or Leased Line over PSN

ETHERNET LINK PROTECTION
The unit performs link aggregation (LAG)
based on 802.3ad requirements.
Dual homing technology (1:1) allows
IPmux-216 to be connected to two
different upstream devices.
PSEUDOWIRE TRAFFIC PROTECTION
Pseudowire traffic can be backed up at
the pseudowire connection level. This
allows setting a different path for the
primary and secondary PW bundles. Bothbundles can be routed to the same ordifferent destinations and operate in the
1+1 and 1:1 modes.
In 1:1 redundancy with two remotedevices the PW bundles in the remoteunits operate in “mate” mode. In thismode each device monitors traffic on amate bundle and transfers data only when
the other bundle is inactive.

IPmux-216
TDM Pseudowire Access Gateway
ETHERNET SERVICE OAM (802.1ag)
The unit uses the end-to-end Ethernetlayer OAM protocol for proactive
connectivity monitoring, fault verification,and fault isolation, according to the IEEE
802.1ag and ITU-T Y.1731 requirements.
LINK OAM (IEEE 802.3ah)
Link-layer OAM according to IEEE 802.3ah
is used for fault indication and loopback
activation response.
MANAGEMENT
IPmux-216 can be configured andmonitored locally via an ASCII terminal, or
remotely via Telnet/SSH, Web browser orRADview.

Preserves investment
in legacy equipment inmigration to PSNManagement traffic can run over a
dedicated VLAN.
The RADview Service Center and Element
Manager packages control and monitor
pseudowire devices and circuits. The
Service Center’s intuitive GUI, “point andclick” functionality and easy-to-follow
wizards increase the efficiency andaccuracy of the service provisioning
process.

IPmux-216 performs RADIUS client
authentication. Using SSH and SSL
encryption protocols allows securecommunication over potentially insecure
IP-based networks.
The Syslog protocol is used by IPmux-216
to generate and transport event
notification messages over IP networks tothe central Syslog server. The Syslog
operation is compliant with the RFC 3164
requirements.
SNMPv3 support introduces a user-based
security model, enhances authenticationand encryption techniques, and ensuresmanagement traffic security.
Each management and service host has aseparate MAC address. As the unit
provides one default gateway, the user
can also specify static routes to enhance
the IP routing capabilities of the
management and pseudowire traffic.
Software is downloaded via the local
terminal, using XMODEM, or remotely,using TFTP. After downloading a newsoftware version, IPmux-216 automaticallysaves the previous version in non-volatilememory for backup purposes. Similarly,
copies of the configuration file may be
downloaded and uploaded to a remote
workstation for backup and restore
purposes.

Data SheetOAM AND DIAGNOSTICS
The following RFC-2495 E1/T1 physicallayer performance statistics are available:
LOS, LOF, LCV, RAI, AIS, FEBE, BES, DM, ES,
SES, UAS and LOMF.
IPmux-216 performs an internal built-in
test (BIT) after power-up. The results ofthe test are visible via the local terminal.
LAN and IP layer network condition
statistics, such as packet loss and packet
delay variation (jitter) are monitored andstored by the device.
Fault isolation, statistics and event logging
are available.
Fault propagation initiates service port
alarms, e.g. E1/T1 LOS, to reflect network
fault conditions. Alarms detected atservice ports are propagated to theremote pseudowire device via the packet
network.

Diagnostic loopbacks can be activatedinband.
Ethernet and IP-layer network condition
statistics, such as packet sequence errors(loss or misorder) and packet delay
variation (jitter), are monitored and storedby the device.
RAD’s TDM PW OAM mechanism verifies
connectivity, measures round trip delay
and prevents pseudowire configuration
mismatch.

SIMPLE NETWORK TIME PROTOCOL
IPmux-216 employs Simple Network Time
Protocol (SNTP) for propagating andreceiving time information on a network,
according to SNTPv4 (RFC 4330)
requirements. SNTP is used to configure
data and time by learning the informationfrom a single or multiple NTP servers. The
clock can be configured to a local time bydefining UTC and DST offsets.
ENVIRONMENT
IPmux-216/H is an environmentallyhardened version intended forstreet-cabinet and cellular-tower
installations.
Notes: The /H version requires temperature
hardened SFP transceivers.
