Memorylink announced the release of two next-generation TDM over IP solutions, the Flanger 4 Plus™ and the Flanger Ultra™, introducing the most cost-effective, reliable, and flexible products of this kind. These multiplexers enable both point-to-point and point-to-multipoint transmission of T1 and E1 traffic, along with wayside data, over Ethernet radio links.

For the carrier considering IP backhaul strategies, this represents a compelling new option

PCS carriers looking for backhaul solutions, and enterprise customers needing T1 and E1 replacement or extension, now have several new, cost-effective options. Memorylink Corp today introduced the Flanger 4 Plus™ and the Flanger Ultra™ TDM over IP multiplexers, setting a new standard for affordable, reliable, and flexible links.

The cost of leased circuits represents a large recurring operating expense (OPEX) for PCS carriers as well as enterprise customers. In the case of PCS carriers, the cost of leased DS1 lines linking carriers' BSC/RNC's to their BTS/Node B's (for GSM and CDMA networks, respectively) is their single largest cost category, representing as much as 20-30% of their monthly OPEX. By pairing Memorylink's Flanger 4 Plus or Flanger Ultra with a compatible wireless broadband radio link, the carrier eliminates the recurring lease expense, and realizes payback periods of less than six months in most cases.

"As IT and telecommunications budgets flatten or decline, there is a growing need to reduce telecommunications network OPEX," said Steve Erickson, Memorylink's Vice President of Sales and Marketing. "Implementing TDM over wireless IP, using Flangers alongside license-free radios provides a very cost-effective, reliable, and fast means of accomplishing this goal. We're seeing tremendous growth in the adoption of this technology. It's being used not only in place of leased lines, but increasingly as a sensible alternative to the older, more expensive licensed microwave links, with major savings in CAPEX. And, these links can literally be installed in hours instead of weeks or months as in the past, so the time-savings is also quite significant."

The Flanger 4 Plus is the next-generation release of the company's best-selling 4-port product, and delivers from 1 to 4 T1 or E1 across an Ethernet link, along with wayside data. It can be installed in both point-to-point and point-to-multipoint networks and offers unmatched flexibility and scalability. It can be installed with a single DS1 activated, and then as requirements increase, a second, third, and fourth DS1 can be added without changing hardware. And the designed flexibility of the product make it equally adept at the most rigorous network requirements, such as GSM and CDMA backhaul, as well as for simpler, more basic PBX extensions.

The Flanger Ultra is the 8-port, rackmount version of Memorylink's TDM over IP solutions. It delivers up to 8 DS1 channels and offers gigabit Ethernet connections to fully utilize the radio capacity. The product can be cascaded to deliver even more T1s and E1s, and as with the 4 Plus, can be installed in point-to-multipoint networks as well. It offers much of the same flexibility and scalability as the 4 Plus, all in a rugged, carrier-grade, higher-capacity package. And of course, both Flanger products are fully compatible, so that an 8-port unit could be installed at a hub location linking one or more sites with the 4-port installed.

"For the carrier considering IP backhaul strategies, this represents a compelling new option", said Steve Erickson. "Choose the ideal Ethernet radio link for your IP requirements, and then add full TDM functionality with the Flanger product line, with the ability to increase or decrease the DS1 to IP mix easily and inexpensively."

Johnathan Hebert, Network Engineer for Pace Cellular in Kaplan, Louisiana is typical of the enthusiastic Memorylink customer. "Some of the areas we cover in rural Louisiana have very little in the way of telecom infrastructure. It's vitally important that we deliver service at the least cost possible, but still maintain our high standard of reliability. Our customers are increasingly using their PCS phone as their only phone. The combination of Memorlyink's Flanger and Motorola's backhaul radios offers the best bang for your buck."

Memorylink's Flanger 4 Plus and Flanger Ultra will be available beginning in September 2009 worldwide and can be purchased through select Memorylink distributors listed at
