=a bidirectional end-to-end STS1 connection, involving a 28 DS1 DSM port at each end

of the connection. This connection traverses on an STS managed OC192 ring.

= 25 bidirectional end-to-end hybrid STS1 & VT1.5 connections, each one involving a DS1 port on the end of the connection. This is implemented by an STS1 cross-connect in NE1, a pass-thru STS1 cross connect in NE3 and 25 VT1.5 cross connects in NE5.

= 3 bidirectional end-to-end hybrid STS1 & VT1.5 connections, each one involving a DS1 port on each end of the connection. This is implemented by an STS1 cross-connect in NE1, a pass-thru STS1 cross connect in NE3 and 3 VT1.5 cross connects in NE4.

Note: Only unprotected connections are shown.
