Common use of Signaling protocol Clause in Contracts

Signaling protocol. 4.1.3.1 SS7 Signaling is AT&T-21STATE’s preferred method for signaling. Where MF signaling is currently used, the Parties agree to use their best efforts to convert to SS7. If SS7 services are provided by AT&T-21STATE, they will be provided in accordance with the provisions of the applicable access tariffs. 4.1.3.2 Where MF signaling is currently used, the Parties agree to interconnect their networks using MF or dual tone MF (DTMF) signaling, subject to availability at the End Office Switch or Tandem Switch at which Interconnection occurs. The Parties acknowledge that the use of MF signaling may not be optimal. AT&T-21STATE will not be responsible for correcting any undesirable characteristics, service problems or performance problems that are associated with MF/SS7 Page 69 of 288 Contract Id: 4777086 Version: 4Q15 – CLEC ICA – 10/19/15 inter-working or the signaling protocol required for Interconnection with CLEC employing MF signaling.
