• Central Office Multiplexing: This equipment is located in the Central Office that derives 24 channels from the DS1 service. There are two types of DS1 multiplexers: DS1 to Voice, or DS1 to DS0.
• Central Office Multiplexer to Multiplexer Connecting Arrangement: This arrangement allows the customers to interconnect at the DS1 level, from an individual channel of one DS3 multiplexer to an individual channel of another DS3 multiplexer.
• Command A Link is available in selected Central Offices and allows the customer to control the reconfiguration of Private Line and switched services on a near real-time basis by means of the special provisioning of these services through a digital cross-connect device.
• Clear Channel Capability allows the customer to transport 1.536 information rate signals through a 1.544 line rate with no constraints on the quantity or sequence of ones and zero bits. The line code is B8ZS.
• SHARP/SHARP Plus (Self-Healing Alternate Route Protection/Self-Healing Interoffice Protection) is provisioned solely on fiber optics and provides a separate facility path for the protection between the Serving Wire Center and the customer premises. It protects the customer against failure of the primary fiber route and the electronics in the local loop. The SHARP Plus feature extends the same alternate route protection into the interoffice portion of the circuit.
• Automatic Loop Transfer: This provides protection against failure of the copper facilities between a customer designated premises and the Serving Wire Center. Protection is furnished through the use of a switching arrangement that automatically switches to a separate DS1 when the working DS1 fails. Environmental Cabinet is available to customers who need to terminate a DS1 on a pole or on the outside of a building.
