Operational Description
The Access Exchange works as an SNMP
compliant switch for optimized T1 access to competitive services. The
Access Exchange optimizes the use of T1s with the ability to route and
translate local and long distance calls. Located on the customer's
premises, this switch allows Interexchange Carriers (IXCs) or other
network providers the ability to offer local service without deploying
local switches. The Access Exchange enables customers to achieve lower
rates on local, long distance, high-speed Internet, and data services
from a single bundled service provider without upgrades to their
existing telephone systems.
Access Exchanges
Features and Advantages
| Features |
Advantages |
|
Integrates voice and data
|
- Reduced monthly data access
costs by eliminating separate 56 Kbps DSS lines
- Economically increases data
speeds to 1.5 Mbps
- Packs under-utilized T1
voice access lines with SNMP/Ethernet-managed data
|
| Provides
dual T1 CSU/DSU connectivity |
Allows dual carrier connections
or increasing bandwidth to 3.0 Mbps
- Minimizes per minute costs
of local and long distance services, while maintaining
existing local number terminations, 411,911, 8XX and other
special calling
- Reduces the need for LEC
analog lines, reducing monthly access costs
- Significant savings over a
PBX with no upgrades to existing customer phone systems
needed

Optional Installation Kit
SpeedwayTM Installation
Kit (for Access Bank or Access Exchange units)
Your installation is literally a snap. This Kit uses locking tabs and
pins, versus screws, to install up to two Access Bank or Access
Exchange units. Customer installation tests have shown up to a 75%
reduction in installation time, as well as up to a 45% smaller
footprint.
