SFP-Format TDM Pseudowire Gateways
The innovative SFP-format MiTOP-E1/T1 and
MiTOP-E3/T3 TDM pseudowire gateways provide
PSN extension of E1/T1 or E3/T3 traffiic. Housed
in a small form factor pluggable (SFP) enclosure,
the MiTOP TDM pseudowire gateways are
designed for quick and simple insertion into any
100BaseFX Ethernet device port with a
compatible SFP socket, making them ideal for
providing transparent TDM circuit services over
PSN.
Running on power derived from the host device,
they require no additional power supply. They
offer a simple and cost-effective alternative to
external, standalone gateway units or
conversion cards, as well as simplify
management and save on space, power
consumption and cabling.
The low-cost SFP plug format is an ideal and
affordable solution for carriers and service
providers delivering circuit extension over PSN,
as well as for similar applications in enterprise
and campus networks.
Pseudowire capabilities
Featuring ASIC-based architecture, the
MiTOP-E1/T1 and MiTOP-E3/T3 incorporate
multi-standard pseudowire support, including
CESoPSN and SAToP. In addition, the devices
support MPLS, MEF-8 and UDP/IP network
protocols.
The MiTOPs maintain large, configurable jitter
buffers to compensate for delay variation
introduced by the packet network.
Four clock modes are supported: internal from a
local oscillator; loopback timing clock recovered
from the TDM network; adaptive clock recovered
from the packet network; and external clock
provided by a dedicated pin on the SFP edge
connector.
The miniature gateways support multi-source
agreement (MSA) product identification codes.
They are hot-swappable and feature a special
release mechanism for easy extraction from SFP
sockets.
Management
The modules can be managed out-of-band via
I
2
C and inband via dedicated Ethernet frames
using a Web browser.
MiTOP can work opposite other MiTOP devices
installed in remote equipment. Alternatively,
they can work opposite gateways that support
CESoPSN and SAToP, such as RAD’s IPmux
pseudowire gateways and Gmux-2000 central
gateways.
