subsidiary or affiliate, where technically feasible, or to any other Party to which each
Party provides local interconnection.
4.4 Common Channel Signaling.
4.4.1 Signaling
4.4.1.1 BellSouth shall offer access to signaling and access to BellSouth’s signaling
databases at the rates set forth in Attachment 3. Available signaling elements include
signaling links, signal transfer points and service control points. Signaling
functionality will be available with both A-link and B-link connectivity.
4.4.1.2 When TC SYTEMS purchases unbundled local switching from BellSouth,
BellSouth must provide TC SYTEMS with unbundled access to BellSouth’s
signaling network at no additional charge or network infrastructure requirement.
Where TC SYTEMS is a facilities based carrier looking to purchase access to
BellSouth’s signaling network, TC SYTEMS shall purchase the appropriate network
components from BellSouth at a market-based rate.
4.4.1.3 When TC SYTEMS provides its own signaling or obtains signaling service from a
third party provider, BellSouth is obliged to provide seamless interconnection
between its signaling network and that of TC SYTEMS or the alternative
supplier(s).
4.4.1.4 Signaling Link Transport
4.4.1.4.1 Signaling Link Transport is a set of two (2) or four (4) dedicated 56 kbps
transmission paths between TC SYTEMS designated Signaling Points of
Interconnection that provide appropriate physical diversity.
4.4.2 SS7
4.4.2.1 When technically feasible and upon request by TC SYTEMS, SS7 AIN Access shall
be made available in association with switching. SS7 AIN Access is the provisioning
of AIN 0.1 triggers in an equipped BellSouth local switch and interconnection of the
BellSouth SS7 network with TC SYTEMS’s SS7 network to exchange TCAP
queries and responses with a TC SYTEMS SCP.
4.4.2.2 SS7 AIN Access shall provide TC SYTEMS SCP access to an equipped BellSouth
local switch via interconnection of BellSouth's SS7 and TC SYTEMS SS7
Networks. BellSouth shall offer SS7 AIN Access through its STPs. If BellSouth
requires a mediation device on any part of its network specific to this form of access,
BellSouth must route its messages in the same manner. The interconnection
arrangement shall result in the BellSouth local switch recognizing the TC SYTEMS
SCP as at least at parity with BellSouth’s SCPs in terms of interfaces, performance
and capabilities.
