Gmux-2000
Hub-Site Pseudowire Access Gateway
The Gmux-2000 is a cost-effective, modular
pseudowire access gateway with high capacity
for extending TDM PDH and SDH/SONET services
over IP, Ethernet and MPLS networks.
Incorporating TDMoIP, CESoPSN, SAToP, and
CESoETH (MEF-8) pseudowire emulation
standards from the IETF, MFA Forum, ITU-T, and
MEF, the Gmux-2000 is an ideal solution for
PSTN access, as well as for PBX and mobile
backhaul. In addition, it enables transparent
delivery of HDLC legacy traffic with HDLCoPSN
support.
The Gmux-2000 is available with a choice of
interfaces, allowing it to relay, concentrate and
groom up to 196 E1/T1, seven channelized T3
or six channelized STM-1/OC-3 links over two
Gigabit Ethernet (GbE) network connections.
The Gmux-2000 works opposite RAD’s IPmux
TDM pseudowire gateways, LA-110 integrated
access devices or Megaplex integrated access
multiplexers, for cost-effective, carrier-class TDM
pseudowire access.
Modules
The Gmux-2000 is a 6U-high chassis, mountable
in a 19-inch ETSI or ANSI rack and houses the
following modules:
• Up to two PSN network uplink modules
• Two control modules
• Three AC or DC power supply modules
• Seven I/O modules (E1/T1, Ch. T3 and
Ch. STM-1/OC-3 interfaces)
• A cooling fans module
Gigabit Ethernet network modules, each
with a pair of redundant Gigabit Ethernet (GbE)
interfaces, support IEEE 802.3, 802.1Q (VLAN
tagging|), VLAN stacking (Q-in-Q) and 802.1p
(priority/class of service).
E1/T1 pseudowire (PW) modules encapsulate
E1/T1 traffic flows for transmission over packet
networks via the GbE network module. The
E1/T1 modules include 28 external E1 or T1
interfaces for connecting individual E1/T1 ports.
STM-1/OC-3 PW modules perform SDH/SONET
multiplexing/demultiplexing of channelized
STM-1/OC-3 trunks into separate, internal E1/T1
circuits. Up to 63 E1 or 84 T1 internal channels
are mapped into VC-12 or VT-1.5 streams to or
from the channelized STM-1/OC-3 interface.
Each STM-1/OC-3 interface module provides a
pair of ITU-T G.957 fiber optic links, supporting
1+1 redundancy according to ITU-T G.783.
Voice compression modules – Gmux-2000
supports up to seven voice compression
modules compatible with the Vmux product line
(see Gmux-2000 on page 155).
Control modules provide the SNMP and
management interfaces, enabling the
configuration and control of the entire
Gmux-2000 system.
