The Global Crossing London Carrier Ring (LCR) metro network extends to all major London telehotel facilities and many private operator premises and boasts around 60 active members, each of whom enjoys the security of a private SDH network hardwired to their own network facilities. Circuits are most frequently provisioned between nominated ports on each operators class 4 or 5 switches, in support of previously agreed interconnect agreements. Individual circuits are invoiced on a monthly basis and may be "B" end shifted to other members at any time and without charge. Similarly circuit cancellations may be actioned at any time.
All moves, changes and additions are actioned via an Extranet service through which circuit inventories may be managed with precision and ease. Physical circuit provisioning at E1 level is often accomplished in less than 12 hours and is guaranteed within 48 hours. Prices are amongst the most competitive in London. Dedicated to its purpose, the LCR has become THE network upon which to purchase capacity for interconnect purposes.
While circuit availability, lead times, prices and service levels are all attractive, the main benefit to members is the membership itself. LCR members offer a compelling combination of routes and tariffs and membership includes many operators whose routes are not easily accessible from other networks. Of course, most members originate as well as terminate traffic and it is these dual objectives that create the trading community that is the essence of the Carrier Ring concept.
Considering the ease with which interconnects can be established and terminated on the LCR (when compared to the hassle of procuring and managing individual circuits from multiple operators) it is easy to understand why the LCR has become Europe’s premier trading hub.
LCR members may upgrade their membership to include ipLCR capability.
The LCR also has an "entry level" membership facility. For those who are unable or unwilling to commit to full membership, Global Crossing offers "Community Membership" of the LCR.
Community Members do not enjoy the dedicated SDH multiplexers and connectivity of full members but instead "share" connectivity into "Community" multiplexers installed in many of the London telehotels. The volume of circuits you require coupled with the number of LCR members you need to connect with will determine whether or not Community Membership is for you. Community Members enjoy the same service levels and connectivity as full members.
Membership terms for both Community and Full members is three years.
