Frame-Relay T1 Connections
Advantages/Disadvantages:
- Versatile (can be easily re-pointed)
- Low cost over long distances (more than 10 miles to destination)
- Extremely Redundant - will reroute based on congestion or line severance between central offices
- Excellent Response and Repair times
- Can support point to multi-point architectures
- Less CIR (Committed Information Rate) than Point-Point connections - roughly 50-75%
- Only offered by Qwest (within the State)
- Expensive for short distance
Frame-Relay circuits are known as PVC's (permanent virtual circuits) meaning that the
traffic over the connection flows through different dedicated paths to its
destination. Because these circuits are "virtual" they have excellent redundancy and
keep the costs down over long distances. CSolutions intercepts Qwest's frame-relay
PVC's over our ATM DS3.
These types of circuits are very versatile and should be seriously considered
for the following types of applications:
- Point to Multi-Point WAN's - because of the virtual nature of these
circuits you can easily attach numerous other PVC's to a single PVC. For
example, you may order a frame-relay T1 PVC for your HQ and tie all your
branch offices to the HQ PVC or to your CSolutions ATM DS3 in any number
of configurations.
- Remote locations - because frame-relay is the same price all over the
state a circuit in St George to SL and Logan to SL and SL-to-SL all cost
the same, which can keep your overall local loop costs down for the entire
project. Frame-relay is available throughout all Qwest Central Offices statewide.
- Flexibility - again because of the virtual nature of the PVC's it is very
easy to repoint your PVC to any other PVC in the frame cloud. For example,
you decide that your St.George office, which is pointing to your SL HQ's for
Internet should be re-directed to CSolutions or to some other office, even some
other company that has a frame circuit. This is a very simple process and can
take place within just a few days or even hours in an emergency.
