A method of providing high-speed data services over the twisted pair copper wires traditionally used to provide POTS (plain old telephone service). Types of DSL include ADSL (asymmetric digital subscriber line), HDSL (high data rate digital subscriber line), SDSL (single line digital subscriber line), and VDSL (very high data rate digital subscriber line).
DSL is typically “oversubscribed” and will rarely provide the bandwidth and reliability that businesses require. However, it is typically deployed as a cost effective redundant connection within many organizations.
T1 / DS1
A T1 (commonly known as a DS1) is a digital circuit delivering 1.5 Mbps of dedicated bandwidth via copper, fiber or wireless media. T1s can be configured to deliver internet access, voice traffic or point to point connectivity. Additionally, T1s can be bonded in an NxT1 configuration via the Multilink Point-to-Point Protocol (MLPPP). Common configurations of bonded T1s include: 2xT1 (3 Mbps), 3xT1 (4.5 Mbps) and 4xT1 (6.0 Mbps).
T3 / DS3
A T3 (commonly known as a DS3) is a digital circuit delivering 45 Mbps of dedicated bandwidth via copper, fiber or wireless media and is the equivalent of 28 T1 lines. T3s can be configured to deliver internet access, voice traffic or point to point connectivity. T3s are typically provisioned in either of the following configurations: rate limited (i.e. 10 Mbps, 15 Mbps, 20 Mbps, etc.) or burstable.
Ethernet over copper (EoC)
Ethernet over copper (commonly known as EoC) is a dedicated circuit that is configured and delivered via twisted copper pairs with an RJ45 handoff at the customer premise. EoC is far more scalable than the T1 / DS1 product and far more cost effective than the T3 / DS3 product. EoC can be configured for internet access, voice traffic, point to point or MPLS connectivity and capacities range from 10 Mbps to 100 Mbps. Many organizations have migrated to EoC products as their bandwidth needs have exceeded the T1 or bonded T1 products.
Fiber based dedicated circuits rely on optical technology to deliver high capacity voice and data circuits to businesses. Fiber solutions support a wide range of ethernet and gigabit ethernet bandwidth options including: 10 Mbps, 50 Mbps, 100 Mbps, 1 Gbps, 40 Gbps and 100 Gbps. These solutions provide the scalability that many enterprises require to support their growing voice and data needs.
