OC-48 definition
OC-48 means OC-48 SONET optical transmission capacity meeting the applicable specifications set forth in Exhibit F.
OC-48. The ANSI SONET (Synchronous Optical Network) transmission standard for high capacity optical telecommunications whose line rate is 2488.32 Mbps. One OC-48 is comprised of 48 STS-1 Synchronous Transport Signal, Level 1 signals which, at 51.84 Mbps, is the lowest level SONET signal. The STS-1 is defined at the electrical level prior to optical conversion. These SONET standards and elements are further defined in the "Bellcore Synchronous Optical Network (SONET) Transport Systems: Common Generic Criteria GR-253-CORE, Issue 2, December, 1995." The optical interface/demarcation for the SONET OC-3, OC-12, and OC-48 tributary signals will occur at the Texas optical interconnect panel. The optical connector standardized for use at Texas locations is the Ultra Polished FC/PC connector with a return loss greater than 45 dB. All optical signals at this demarcation must equal or exceed the applicable Bellcore specifications, referenced above.
OC-48 means bi-directional OC-48 optical transmission capacity meeting the specifications set forth in AT&T's Technical Reference 54078, as revised from time to time.

Testing Standards Texas will test and turn-up the OC-3, OC-12, and/or OC-48 circuits to the applicable demarcation point per this Agreement. The tests will be performed per the applicable manufacturer's test specifications as it applies to the specific type of traffic hand- off. The system will also be tested for a long-term stability test running end-to-end for a period of 24 hours; Bit Error Rate (BER) performance shall be no greater than 10-(1)(1). Five (5) days prior to testing, Texas will notify Virginia verbally and in writing of Texas' intent to complete testing of the applicable circuit activation: Virginia will have the right but not the obligation to witness the activation testing. Copies of test results will be provided to Virginia upon completion of the activation tests. If Virginia is not present at time of testing, a copy of the test results will be forwarded to same. After Texas delivers circuits to PSINet, PSINet shall test same in accordance with the following criteria, and accept installation segments of IRU Capacity only after it meets the following: - Optical signal strength and other characteristics are within industry standards at each termination point as measured with appropriate test equipment. - Backup path verified by testing fault switching hardware applicable to the circuit being provided (test of 1:1 redundancy on the optronics). - Packet data passed with payload contents of 4500 bytes of all zeros for twelve hours registering frame/code violations or other bit errors at a rate not to exceed 10-(1)(1...
