OC12 Services Overview
OC12 Definition? OC12 translates into four OC3's or 336 T1's at 622 Megabits per second. OC12 is the abbreviated term for Optical Carrier level 12, used to specify the speed level of fiber optic networks. Its speed is measured through SONET (Synchronous Optical Network) standards. OC 12 circuits work as a reliable fiber optic backbone for large networks with large IP bandwidth needs, VoIP / Voice over IP, Video Conferencing, and Internet applications. OC12 networks require low maintenance, but can take longer to upgrade than Gigabit Ethernet when adding bandwidth rings to increase speeds and capacity to a higher level.
A common method of back up used with OC12 ring is called a "bi-directional ring topology." This bi-directional ring is a physical topology which deploys two sets of fiber strands. The ring is a physical fiber ring more resembling an oval shaped loop.
The first strand to an OC12 connection is for sending and receiving. The second strand will reroute traffic from the original OC12 transmission in another direction should the first strand break or malfunction. Bi-directional ring topology help ensures constant reliability within an OC-12 fiber based network.
The primary function is to take, synchronize, and transport data, video, and voice at the speed of 622 Mbps reliably. Common sources of this data include ATM switches, T1 and T3 multiplexers, and large IP networks.
STS-12 is the abbreviated term standing for Synchronous Transport Signal level 12. STS and SONET OC carry the same electrical equivalent; therefore STS-12 is the equivalent to SONET level OC-12.
STS-12 is an optical carrier frame consisting of the following characteristics:
SPE (Synchronous Payload Envelope), SOH (Section Overhead), POH (Path
Overhead), and LOH (Line Overhead).
SPE is the electronic envelope that carries the data over the OC12 otherwise
known as the Payload.
SOH maintains all the links within OC-12 while relaying line status to
the end user. The information within SOH includes the status of transported
data, the notification of messages, as well as alarm levels.
POH is responsible for the functionality of the data envelope in OC-12
while in transit. Such functionality includes vital information for the
management of end-to-end networks. POH travels within the data envelope
until the data is de-multiplexed through multiplexing equipment.
LOH controls the reliability transit of the data over an OC12 line.
LOH and SOH combined on a SONET OC12 network create what is referred to
as TOH (Transport Overhead). TOH is one of the elements responsible for
signaling and control over OC12 network lines.
The Four OC12 Layers:
Photonic Layer - This layer of an OC12 converts transmitted electrical signals that usually travel via copper into optical signals then transfers them back into electrical signals at the end of the transmission.
Section Layer - This layer monitors the condition and progress of the OC 12 signal in route to and from signal amplifiers and SONET hardware.
Line Layer - This layer monitors and provides administration of multiplexers as well as provides synchronization of multiple signals. Through this synchronization, the OC12 is able to put all the signals into one stream of traffic for high speed transfer.
Path Layer - Assembles and disassembles transmitted data and voice into frames.

IP Addresses Allocation: IP address space is a finite resource that is an essential requirement for all Internet Access products. Every customer, from dial-up and ISDN, all the way to OC-3 packet over SONET IP (POSIP), needs IP addresses for Internet connectivity.
Customer IP address space can come from several different sources:
Grandfathered from InterNIC (usually large organizations that have existed on the Internet pre-1998).
Internet Assigned Numbers Authority (IANA) (IANA usually only releases address space to the primary registries themselves, but they've been involved with assigning Class A networks in the past. They have a current role in the assignment of space from Class A network 24 which is reserved for use by cable companies providing commercial Internet service.)
Assigned from a primary registry (ARIN, RIPE, APNIC).
Portable space from another Internet Service Provider (ISP) (usually address space below the 206.x.x.x range and probably quite old).
Non-portable space from another ISP (for customers that intend to multihome with another ISP).
The company allocates address space to customers on a per-justification
basis. In other words, there is not a set amount of address space that
is assigned to a particular type of service (i.e., a T1 customer could
conceivably have a legitimate need for more address space than an OC-3
customer could). For the technical purpose of IP justification, the size
of the pipe (bandwidth) is not relevant.

Our technical support teams are available 24 hours a day, 365 days a year to answer your questions and do whatever we can to make your government organization run smoothly.
OC12 Network Access - POS vs. ATM
OC12 service uses Packet over SONET (POS) technology instead of Asynchronous Transfer Mode (ATM) to maximize bandwidth. POS places the IP packet onto Point-to-Point Protocol (PPP) then SONET, which optimizes bandwidth and reduces inefficiencies in data delivery. Customers currently using OC3 service can expand their bandwidth by simply upgrading to OC12 service, rather than ordering multiple OC3 lines. Service Level Agreements are extended to OC12 customers for availability, installation, latency (speed), packet delivery, and proactive outage notification.
OC12 Network Implementation Plan
Upon placement of an order for dedicated connectivity, each US customer is assigned an installation engineer who serves as the single point of technical contact between the customer and our carrier prior to installation of service, and for thirty days after the successful establishment of connectivity. As part of establishing new dedicated connectivity to a site, the installation engineers help customers with many of the issues that would otherwise make connecting to the Internet difficult. The Carrier allocates IP address space to and establishes DNS service for each customer as appropriate. We can provide primary and secondary DNS for customers, or customers can provide primary DNS with the carrier providing secondary DNS support: We generally recommend that customers who list many systems in their DNS supply their own DNS.
Throughout the entire installation process, installation engineers provide input to customers to help them plan for their connectivity, and to help them create effective solutions that will be as simple as possible to implement. The installation engineers are highly skilled in helping customers with any technical background needed to establish their Internet connectivity.

By routing over redundant, high-speed connections to all major Internet backbones, this service provides highly reliable robust delivery of your content, applications and communications throughout the Internet.
Internet Network Backbone - Detail
Using its patented technology and the existing Internet network infrastructure, we created an innovative way to route data and avoid the Internet's points of congestion. Rather than provisioning traditional single ISP network access, Performance IP service intelligently routes across up to 8 integrated NSP networks in the Private Network Access Points (P-NAPs). This insulates your traffic from the risk of network outages, providing reliable, stable and predictable connectivity.
Intelligent Technology
We have developed proprietary route control technology, which overcomes the limitations of traditional routing policies. This technology monitors the performance of each Internet backbone, routing your traffic across the best path, providing fast and more reliable data delivery than traditional routing methods. The route control technology considers path characteristics like latency, packet loss, route stability and congestion when making routing decisions. Decisions are made dynamically and automatically to account for network performance changes, without the need for manual intervention.
