FLANGER™
 If you are responsible for wireline or
PBX systems, you need to know about Flanger from MemoryLink.
Flanger is a low-cost solution that enables point-to-point
tunneling of TDM traffic T1 and E1 across dedicated, point-to-point wireless
Ethernet devices such as the Canopy Wireless Broadband Platform from
Motorola.
MemoryLink designed Flanger for users of medium to
large-scale telecommunication systems looking to reduce costs and enhance
reliability of their T1 or E1 connectivity.
Flanger:
- Dramatically reduces monthly lease line costs for
multiple T1 and E1 lines;
- Promises absolute reliability that your point-to-point
T1 or E1 lines will work all day, every day;
- Connects PBX systems in remote office and campus
environments;
- Eliminates monthly leased landline charges and enhances
reliability by replacing T1 or E1 connections to cellular towers;
- Is ideal for remote emergency/disaster recovery or
special events which requires an immediate bank of phones for portable
cellular base stations;
- Protects investment in legacy equipment;
- MemoryLink's exclusive Shapeware means that Flanger is
totally scalable giving users more control, more flexibility and more
value.
The Low Cost SolutionFlanger ™ from MemoryLink ™
enables point-to-point multiplexing of T1 & E1 traffic across wired and
wireless Ethernet devices. This small, simple-to-use unit provides seamless
transport of T1 & E1 across an Ethernet link; allowing for dramatic cost
savings compared to the cost of conventional leased lines. Flanger can
support from one to four T1’s or E1’s per link. Flanger also allows
multiplexing of LAN traffic along with the T1/E1 payload. The LAN traffic
utilizes the available bandwidth in the connection to deliver even more
value.
Designed For Wireless
The MemoryLink system uses a unique algorithm to transport the T1 & E1
data streams. This algorithm has been optimized for wireless Ethernet
transport. Because of the potential for changing conditions that could
affect wireless network throughput, the Flanger unit provides the capability
for recovering from data loss, without propagating the errors to following
frames. This is accomplished with MemoryLink’s Channel Look-Ahead™ and
Programmable Channel Optimization™ features.
Easy Setup And Configuration
Within the Flanger Utility user interface, Profiles are provided by
MemoryLink for each tested Ethernet radio. These Profiles are the optimized
values of the combination of Packet Size and Buffer Depth that achieve best
performance and reduced latency. Additionally, custom Profiles may be
specified by the user. This allows a complete link to be setup in hours
versus waiting for the Telco to provision a T1/E1 circuit. Because
Flanger provides physical pass-through of the T1 & E1 link, no special
configuration or setup is required regardless of the format (e.g.,
fractional, channelized, clear channel, checksum on or off, etc.). The T1 &
E1 signals are precisely repeated using a clock locked to the incoming line.
In case of signal interruption at the source, no additional
resynchronization is required at the Flanger device level. No special setup
is needed to enable such things as fractional T1; whatever is impressed upon
the T1 con-nection at one end appears unchanged at the other.
Flanger Gets Smarter Over Time
With MemoryLink’s exclusive Malachi™ architecture, Flanger’s hardware
becomes interactive, reprogrammable and reshapable– with scalability and
greater dimensionality. Flanger is superior to competitive technologies that
have built-in obsolescence and deliv-ers a far greater value over
silicon-based circuitry.
Network Connectivity
Flanger can be deployed across a networked environment using wireless
broadband, wired Ethernet, or a combination. Channel Look-Ahead continuously
estimates the variation of arrival time; in conjunction with the
Programmable Channel Optimization feature, the MemoryLink system can deliver
optimum reliability under changing network conditions. For example, when
used with a wireless system, Flanger provides “last mile” T1 & E1 transport
across distances limited only by the selected radio’s capabilities. It is an
ideal, affordable solution for connecting PBX systems in remote office and
campus environments. Flanger can also sup-plant wire-line T1 & E1
connections to cellular towers, eliminating monthly leased landline charges
as well as the associated problems.

using the differ-entiated services field to prioritize T1/E1 traffic over
Flanger routed LAN traffic.T1 bandwidth (1.544 Mbps) X the number of T1’s
plus 256 Kbps of overhead in each direction per T1, thus occupying a total
of 3.6 Mbps per T1.E1 bandwidth (2.048 Mbps) X the number of E1’s plus 256
Kbps of overhead in each direction per E1, thus occupying a total of 4.6
Mbps per E1.
Applications
Remote PBX
One common application involves the inter-connection of Private Branch
Exchanges (PBXs) in multiple locations. Connected as shown in the figure
below, Flanger links can provide excellent service and reliability at a
fraction of the cost of leased T1 or E1 lines.
Cellular Backhaul
Another application is to connect cellular telephone base station sites to
the Mobile Telephone Switching Office. Flanger can be the key to substantial
cost savings and enabling a completely independent and maintainable network.
