Voice Quality Testing across multiple networks (T1, E1, T3, E3, OC-3, OC-12, VoIP, Wireless, and Landline) are all available.
Those steps start with the MX5, a 20Gbps router that features 20 Gigabit Ethernet SFP interfaces and a variety of WAN interfaces: four to eight OC-3s, two to eight OC-12s, one to four OC-48s, and eight DS-3s.
The SONET OC-12 was then upgraded to a more robust SONET OC-48 with T-3 lines by the end of 1999.
The plot in Figure 6 shows a simulation of an OC-12 photonics clock generator from a 19.44 MHz crystal, assuming that the VCO has a noise profile, L(fm), that is -115 dBc/Hz at an offset of 100 kHz from the carrier.
The key to providing global companies with high-performance Internet access is Concentric's redundant, OC-3 / OC-12 ATM backbone, and strategic private and public peering architecture that ensures Hanaro's Internet traffic will flow quickly and securely.
For instance, to deliver OC-12 (STM-4) service using SONET gear to a total of four customers on a ring, a carrier must deploy an OC-48 (STM-16) ring with costly OC-48 (STM-16) equipment at each customer premise.
And by year-end, it will be sampling a another new device, the IBM Processor for Network resources, aimed at the OC-12 (622 Mbps) high-speed interconnect and backbone network edge space, and which it says will be in OEM products by the second half of next year.
At its core is a redundant 622 Mbps OC-12 ATM backbone based on four CoreBuilder 9000 enterprise switches.
The Conversion Center is Transition's 16-slot chassis-like design which can convert many networking protocols, including unshielded twisted pair to fiber conversions for Ethernet, Fast Ethernet, ATM, FDDI and Token Ring, as well as single- to multi-mode fiber conversions for these environments as well as Gigabit Ethernet and OC-12.
ADC's OptEnet Media Converters transition and protect critical Ethernet, OC-12, and Gigabit Ethernet circuitry at the desktop and the data center.
This performance is said to surpass Telcordia's GR-253-CORE requirements for OC-3 to OC-12 optical rates, and the ITU-T's G.813 Option 1 and 2 specifications for STM-1 to STM-4.
The OptiView WAN Analyzer allows network engineers to identify all network elements that utilize OC-3 or OC-12 WAN links, perform full RMON2-based remote monitoring, gather detailed traffic statistics, and filter an capture cells and packets on network links at line rate.
