IPmux-11
TDM Pseudowire Access Gateway
DESCRIPTION
• IPmux-11 is a TDM pseudowire
access gateway extending
TDM-based services over packet
switched networks. It also serves
as an Ethernet-based access
device.
TDMoIP PERFORMANCE
• IPmux-11 provides a legacy over
FEATURES
• TDM pseudowire CPE/CLE,
•
•
•
•
•
•
•
offering TDM circuit
emulation over a
packet-switched network
(PSN) and controlled
Ethernet access
Built on TDMoIP technology,
implementing the emerging
IETF, MFA Forum, ITU-T and
MEF standards for
Pseudo-Wire Emulation
Edge-to-Edge (PWE3)
E1/T1 emulation over MPLS,
IP and Ethernet networks
Support for both framed (full
or fractional) and unframed
E1/T1
Configurable jitter buffer to
compensate for network
packet delay variation
Dedicated external clock
port
Ensures TDMoIP priority by
QoS marking: ToS, VLAN
priority or EXP bits
Operates opposite other
members of RAD’s TDMoIP
family of products
(IPmux-1E, IPmux-14,
IPmux-8/16, Gmux-2000,
Megaplex ML-IP)
• One Ethernet network port;
two Ethernet user ports,
offering
Transparent Ethernet
bridging
User data bandwidth and
access control through
rate limiting and VLAN
filtering
VLAN tagging and double
tagging
• Typical applications:
E1/T1 (voice or data)
leased line replacement
PBX PSTN access
Multiservice
TDM/Ethernet CLE/CPE
• Management via ASCII
terminal, Telnet host, Web
terminal or SNMP-based
network management
station
• Provisioning and monitoring
of TDMoIP services using
the RADview Service Center
for TDMoIP applications
• Compact, 1U high enclosure
PSN solution transmitting E1/T1
streams over packet switched
networks. The device converts the
data stream from its user E1/T1
port into packets for transmission
over the network. The addressing
scheme of these packets is IP or
MPLS. These packets are
transmitted via the IPmux-11
Ethernet network port to the PSN.
A remote TDMoIP device converts
the packets back to TDM traffic.
• High-performance buffering and
forwarding techniques are used to
achieve end-to-end processing
delay as low as 3 msec.
• Configurable packet size allows to
achieve proper balance between
PSN throughput and delay.
• A jitter buffer compensates for
packet delay variation (jitter) of up
to 300 msec in the network.
• Assigned, IANA-registered UDP
port number for TDMoIP
simplifies flow classification
through switches and routers.

TDMoIP QoS
• IPmux-11 supports VLAN tagging
and priority labeling according to
802.1p&Q. TDMoIP packets are
assigned a dedicated VLAN ID
and 802.1p bit.
• The ToS or Diffserv of the
outgoing TDMoIP packets are
user-configurable. This allows the
TDMoIP packets to be given a
higher priority in IP networks.
• EXP bits are used for QoS marking
of the TDMoMPLS traffic in MPLS
networks.
TDMoIP TIMING
• Synchronization between TDM
devices is maintained, by
deploying advanced clock
distribution mechanisms. The
clocking options are:
Internal – the master clock
source for the TDM circuit is
provided by IPmux-11’s internal
clock oscillator
Loopback – the transmit clock is
derived from the E1/T1 port’s
receive clock
Adaptive – the clock is
recovered from the PSN
External – an external clock
source to synchronize the device
via its station clock port.
• System clock ensures clock
resilience by using master and
fallback timing sources for clock
redundancy. IPmux-11 also
provides system clock output via
external clock connector.
TDM INTERFACE
• One standard E1 or T1 port
provides connectivity to any
standard E1 or T1 device.
• E1 and T1 interfaces support the
following:
Integral LTU/CSU for long haul
applications
G.703 unframed and G.704
framed modes
CAS and CRC-4 bit generation
(E1)
D4/SF and ESF framing (T1)
Robbed bit (T1).
ETHERNET INTERFACE
• IPmux-11 provides the following
Ethernet ports:
One network port (UTP or fiber
optic)
Two user ports (both UTP or
UTP and fiber optic).
• Each Ethernet port supports:
Port-based rate limiting for
bandwidth control
Port-based VLAN membership
for ingress traffic restriction
Port-based VLAN tagging
Double VLAN tagging (VLAN
stacking)
Bridging and filtering.
ETHERNET CAPABILITIES
• IPmux-11’s internal Layer-2
Ethernet switch provides three
Ethernet ports. One port serves as
a network interface and the other
two serve for user Ethernet traffic.
• Each Ethernet port supports:
Configurable port-based rate
limiting for bandwidth control
Configurable port-based VLAN
membership for ingress traffic
restriction
Configurable port-based VLAN
tagging; a VLAN tag is added
resulting in a double tagging
(VLAN stacking) when an
already tagged frame is
switched.
• The device supports standard IP
features, such as ICMP (ping),
ARP, next hop and default
gateway.

DIAGNOSTICS
• External and internal loopbacks
can be used to check TDM link
connectivity.
• The following E1/T1 physical layer
performance statistics are
available: LOS, LOF, LCV, RAI,
AIS, FEBE, BES, DM, ES, SES, UAS
and LOMF.
• IPmux-11 performs an internal
built-in test (BIT) after power up.
The results of the 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 and stored
by the device.
• Fault isolation, statistics and event
logging are available.
• To enhance fault condition
reporting capabilities, remote
IPmux-11 transfers RDI, LOS and
AIS conditions received from the
remote E1/T1 device to the local
E1/T1 device via the PSN.
MANAGEMENT
• IPmux-11 can be configured and
monitored locally via an ASCII
terminal, or remotely via Telnet,
Web browser or RADview.
• Management traffic can run over a
dedicated VLAN.
• The RADview Service Center and
Element Manager packages
control and monitor TDM over IP
(TDMoIP) devices and circuits.
The Service Center’s intuitive
GUI, “point-and-click”
functionality and easy-to-follow
wizards increase the efficiency
and accuracy of the service
provisioning process.
• Software download is supported
via the local terminal, using
XMODEM, or remotely, using
TFTP. After downloading a new
software version, IPmux-11
automatically saves the previous
version in non-volatile memory for
backup purposes. Similarly, copies
of the configuration file may be
downloaded and uploaded to a
remote workstation for backup
and restore purposes.
