Corporate Customer Network Migration Strategy
Legacy Network for leased circuits
Existing Network Topology
will be reconfigured so that existing muxes will become
access muxes to the Newbridge Network.
- based on mux-to-mux T1 links
- requires case-by-case consideration at the Network level for tandem circuits
- offers little Network Management
This will produce the following results:
The New Network will consist of the Newbridge Nodes, which form the backbone cross-connection points,
and Access Muxes, which feed the Newbridge Nodes.
- Current Interexchange T1 links that have muxes at either end will initially become
links to a Newbridge Node, during the migration/cutover. T1 capacity can thereafter be
- Muxes at hub points that also contain a Newbridge Node will initially become access muxes to
the Newbridge. Grooming will make some available for use in Remote Offices to the Newbridge
- Improved Network Management for Customer Circuits which pass through Non-Newbridge muxes.
- A Mux at a Remote Office will become an Access Mux for the Newbridge Network and will be
visible on the Newbridge Network Management System.
- There will be one Network instead of two separate Networks with different Provisioning
and Maintenance capabilities.
- Provisioning of tandem circuits will no longer require case-by-case design at the Network Level
but only at the Access end points.
- In 1996, two DE4ES muxes in Nelson were put facing the DACS in TSTT
- In 1997, an FCD1-4 was placed in Amoco Galeota, facing the Newbridge
in Point Lisas. This replaced the FCD1-to-FCD1 mux-to-mux link that
had existed between Amoco Galeota and Point Lisas. This reconfiguration
permitted the provisioning of Pending Orders for Amoco.
- In late 1997, one T1 from one mux in Nelson was reconfigured to point to the
Newbridge in Nelson. This became the crossover mux between the
mux-to-mux network and the Newbridge Network. This mux is now full,
causing a backlog of Pending Orders await further muxes to be pointed to
