OC-12 definition

OC-12. The ANSI SONET (Synchronous Optical Network) transmission standard for high capacity optical telecommunications whose line rate is 622.08 Mbps. One OC-12 is comprised of 12 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."
OC-12 means OC-12 SONET optical transmission capacity meeting the applicable specifications set forth in Exhibit F hereto.
OC-12 means a dedicated, point to point, high capacity, full duplex channel along the Qwest Network with a line speed of approximately 622.08 million bits per second synchronous serial data.

Examples of OC-12 in a sentence

  • EEL Transport is available in DS0, DS1, DS3, OC3, OC12 and higher bandwidths as they become available.

  • OC-12 Service operates at 622.080 Mbps with 12 separate STS-1 signaling paths.

  • OC-12: Optical Carrier level 12 signal transmitting at 622.080 Mb/s.

  • Subject to the terms and conditions of this Agreement, PSINet may order Bandwidth in increments from OC-12 to OC-48 along any portion of the Available System.

  • In consideration of IXC's maintenance obligations hereunder, PSINet shall pay IXC a monthly fee of * per OC-12 Equivalent Mile per month (on lower capacity, * per DS-3 Mile per month) for each OC-12 (or its equivalent) provided by IXC to PSINet hereunder.

  • In the event PSINet requires capacity in units other than OC-48 or OC-12 (for example, an OC-3 or DS-3) it will pay IXC's fees for multiplexing as set forth in Exhibit H hereto (except as set forth in the last sentence of Section 2.3).

  • If ordered by PSINet, IXC will make Available to PSINet at least 10,000 OC-12 Equivalent Miles in each Six-Month Period.

  • Multiplexing charges as set forth herein will not apply to any bandwidth so transferred unless and until PSINet reconfigures such bandwidth concurrently with such transfer or, with respect to a particular route, PSINet orders OC-12 capacity on such route.

  • The acceptance criteria for DS1, DS3, OC-3, OC-12, OC-48, OC-3c, OC-12c, and OC-48c circuits between Qwest Network Interface points is to provide the performance levels shown below during a 60 minute test period.

  • Such equipment will be connected to Ameritech's unbundled Network Elements through a mid-span meet arrangement at the DSO, DS1, DS3, OC3, OC12, OC48 and where available, STS-1 rates, subject to any technical limitations on the distance between Wire Centers.
