Overview of Work
Good Afternoon, This change is being delivered as part of the overall ANT project which has been fully tested prior to deployment. The circuit impacting downtime will be a maximum 240 minutes during the change window.  
Kind Regards. Faith Muskett

Overview of Work	This migration activity is part of the overall Access Network Transformation Project (ANT); The ANT project is necessary to deliver continuous and sustainable growth across the TTT access network and is part of the wider network brilliance programme.
ANT - METRO (ALL SERVICE) MIGRATION  
In order to implement the new Access Network (ANT) there is a requirement to migrate all services at the METRO exchange onto the ANT Topology. 
We will complete this by moving the existing backhaul from the EX4200 onto the MPS directly. This forms the correct ANT Topology. If the Metro node is also a collector node then the backhaul may connect directly to an NPE instead of the EX4200; in which case we would need to move the backhaul off the NPE and onto the MPS directly. 
We will be moving all services; (1. PPP; 2. EAD; 3. EOFTTC  4. Multicast 5. EFM 6. Voice 7. Management) Traffic from all Legacy connections at this exchange onto the new ANT Topology. 
Service termination for direct Business Services will be moved from NPE/NGE to the MPS. 
We will also be moving Residential; Business & Reseller PPP Traffic from all MSANs/DSLAMs along with Residential and Business FTTC Traffic; at this exchange onto the new ANT Topology and onto the NGE for subscriber termination via pseudo wire headend termination. 
Engineering resource will be aligned to mitigate the risk of 2x Switches being worked on at the same time. Effective comms and planning will allow multiple resources to complete multiple services on the same night. 
Customers should only get a combined impact of 0.5 hours during the implementation window. 
This will migrate all services migrate all services at the metro exchange onto the ANT Topology. 
We will be moving all services; (PPP; FTTC; EFM EAD; EoFTTC; Multicast; Voice & Management) Traffic from all Legacy connections at this exchange onto the new ANT Topology. 
Service termination for direct Business Services will be moved from NPE/NGE to the MPS. 
We will also be moving Residential; Business & Reseller PPP Traffic from all MSANs/DSLAMs along with Residential and Business FTTC Traffic; at this exchange onto the new ANT Topology and onto the NGE for subscriber termination via pseudo wire headend termination. 
Multicast; Voice and Management Migration will also take place during the same maintenance window. Frome Mells Warminster
