IPmux-155L
Hub-Site Pseudowire Access Gateway

Multiservice
pseudowire gateway

 High capacity pseudowire gateway, transporting TDM traffic (fully populatedchannelized STM-1 stream or up to 32 E1 channels) over packet-switched
networks

converging TDM voice Pseudowire technology, compliant with IETF, MFA Forum and ITU-T standards
for Pseudowire Emulation Edge-to-Edge (PWE3)

or data services over Aggregation of 32 fiber optic or electrical Fast Ethernet interfaces into fourGigabit Ethernet links

packet-switchednetworks

 1U or 2U, 19” enclosure with redundant power supply and fan units

IPmux®-155L is a pseudowire gateway thattransports TDM traffic (originating fromlegacy circuit-switched networks) overpacket-switched networks (PSNs). This isachieved by converting TDM data streams
coming from the TDM ports into packets
transported over the PSN.

IPmux-155L includes the following ports:
1 + 1 redundant STM-1 or 32 E1 ports

Four Gigabit Ethernet ports with trafficprotection

32 fiber optic or electrical Fast
Ethernet user ports.

The Access CompanyIPmux-155L
Hub-Site Pseudowire Access Gateway

The unit is used for:SDH INTERFACEETHERNET INTERFACEThe SDH interface provides direct accessto the Synchronous Digital Hierarchy(SDH) transmission cores at the STM-1level (155.520 Mbps).

IPmux-155L features the following PSNports:


Four Gigabit Ethernet ports with
SFP-UTP combo connectors

SDH mapping mechanism collects payload
from 63 internal E1 streams and directs it
towards STM-1 link.

32 Fast Ethernet ports with fiber optic
SFP or UTP connectors.

Aggregating traffic from remotepseudowire devices, such as IPmux-24
or IPmux-2L, at a small PoP or CO,
while eliminating the need for an
additional Ethernet switch.
Transporting STM-1 or E1 traffic overPSN, saving TDM leased line costs.

PSEUDOWIRE FUNCTIONALITY
The ASIC-based architecture provides arobust and high-performance pseudowire
solution with minimal processing delay.
The unit employs SAToP, CESoPSN andTDMoIP pseudowire encapsulation methods.
Proper balance between PSN throughput
and delay is achieved via configurable
packet size.

The physical STM-1 ports can be orderedwith field-replaceable SFP transceivers
with optical interfaces, for meeting a wide
range of operational requirements.
1+1 APS line redundancy ensures rapid
restoration of service in case of STM-1 linefailure.
AU4/TU12 pointer operation complies withG.783, G.707 requirements. Tracemessages with 16-byte sequences (J1 andJ2 bytes) are generated and monitored.

A jitter buffer compensates for packet
delay variation (jitter) of up to 200 msec
in the network.

E1 INTERFACEPSEUDOWIRE TIMING
End-to-end synchronization between
circuits is maintained by the adaptive clock
recovery mechanism.

32 external E1 interfaces provide
connectivity to any standard E1 devices.
E1 interfaces feature:
Integral LTU for long haul applications

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

G.703 unframed and G.704 framedmodes

The system clock uses master and fallback
timing sources for clock redundancy.
IPmux-155L also provides system clock
input and output via an external clock port.

CAS and CRC-4 bit generation (E1).

The GbE interface operation complies withIEEE 802.3, 802.1Q and 802.1p
requirements.
Link aggregation is performed as per
802.3ad (with or without LACP). This
enables operators to use up to four
Ethernet links as a single virtual interface,sharing traffic load and providing linkresiliency.
G.8032 ETHERNET RING
The unit employs a G.8032 Layer-2
Ethernet ring mechanism to protect
against link and node failures.
ETHERNET OAM
IPmux-155L provides OAM to monitor andtroubleshoot the Ethernet network andquickly detect failures. The OAM
mechanism operates according to IEEE
802.3ah requirements for fault indicationand loopback activation response.

Data SheetETHERNET CAPABILITIESSYSTEM REDUNDANCY

IPmux-155L includes an internal bridge,
operating in VLAN-aware andVLAN-unaware modes.

System architecture provides redundancy
at different levels:

VLAN stacking can be used for traffic
separation between different users orservices, by defining a service provider
VLAN ID per customer or service. WhenVLAN stacking is used, a service provider
VLAN tag is added to the user traffic andremoved from network traffic. Bothservice provider VLAN ID and serviceprovider VLAN priority can be defined.
User traffic can be queued and prioritizedaccording to VLAN priority andToS/Diffserv.
Ingress and egress rate can be limited peruser and network ports.
Policing and classification of the traffic
flows are performed between any ingress
and any egress Ethernet port of thedevice. IPmux-155L monitors traffic withspecified flow parameters, allocatesbandwidth, forwards traffic to different
queues according to classification
parameters etc.

GbE interface with 802.3ad-based linkaggregation

STM-1 1+1 line redundancy with lessthan 50 ms restoration of service incase of link faults

Redundant power supply units andfans.

MiRICi-E3T3 SUPPORTWhen equipped with a removable
MiRICi-E3T3 module (ver. 2.5), a fiber FE
port can operate as an E3 or T3 port,
forwarding LAN packets to TDM-based
WAN. When operating in the T3 mode,
MiRICi-E3T3 modules are fully controllable
via IPmux-155L management application.

Lowers Opex of TDM
service by utilizing
packet infrastructure

Note: IPmux-155L equipped with the AC or 48
power supply modules supports up to 16MiRICi-E3T3 units.
When equipped with two high-power ACHP or 48HP
power supply modules, IPmux-155L can host up to
32 MiRICi-E3T3 units.

MANAGEMENT CAPABILITIESOAM AND STATISTICS

The unit can be managed using different
ports and applications:

Comprehensive monitoring and diagnostic
capabilities include port status indicationand statistic counters for Gigabit Ethernetand STM-1 interfaces.

DIAGNOSTICS



Local out-of-band management via aterminal connected to the RS-232 port

Remote out-of-band management via
the dedicated 10/100BaseT port

Remote inband management via theGbE or FE interface. Remotemanagement is performed using Telnet
or RADview, RAD’s SNMP-based EMS.

Software is downloaded via the local
terminal, using XMODEM/YMODEM, orremotely, using TFTP/FTP.
The Syslog protocol is used by IPmux-155L
to generate and transport event
notification messages over IP networks tothe central Syslog server. The Syslog
operation is compliant with the RFC 3164
requirements.

External station clock source via
station clock port, providing
out-of-band synchronization.

RAD’s TDM PW OAM mechanism verifies
connectivity and prevents pseudowire
configuration mismatch.

For diagnostic purposes, IPmux-155L
maintains a cyclic event log file that stores
up to 2048 time-stamped events and areal-time current alarm list.

ALARM REPORTING

To verify the TDM link integrity,
IPmux-155L provides local or remoteloopbacks on the VC-4 and E1 interfaces.

The device includes a dry-contact
connector for reporting alarms to external
equipment. The connector also has anexternal alarm input for monitoring
external sensors.
TIMING
IPmux-155L features a flexible clock
mechanism using external and internaltiming signals coming from:SDH clock (8 kHz)

2.048 MHz clock recovered from a PW
flow, E1 line or GbE port (Sync-E)

User-activated BER tests can be generated
to analyze E1 streams.
An internal built-in test (BIT) performed
after power-up checks the internal
circuitry of the unit. The results of the test
are visible via the local terminal.
