|
Limited availability |
|
| Physical Circuit |
|
T1 circuits are engineered for digital data transmission and may be delivered via fiber optic. |
|
DSL connections are made from voice-grade copper telephone circuits, quality of service is lower. Fiber, bridges or coils on circuit will prohibit DSL. |
|
| Business Use |
|
Proven in mission-critical situations. |
|
Unproven in mission-critical situations. |
|
| Reliability |
|
Dedicated T1 connections are rock-solid and based on proven, mature technology. High availability and reliability. |
|
DSL is a low-margin service and thus repairs are not top priority for the telcos. |
|
| Connection |
|
T1 service offers private point-to-point dedicated connection between the customer and 42, Inc. - there's no middleman. |
|
DSL is made via a shared, switched ATM network. A number of customers are aggregated at multiple single connection points (DSLAM in each DSL CO). Each aggregation point is a potential point of failure. |
|
| Circuit Repairs |
|
FCC mandates a one-hour repair response from telco providers, once a trouble ticket on T1 circuits is opened. |
|
DSL connections are treated as voice-grade circuits. This means the telco will not respond to trouble tickets until the next business day. |
