The OC-3c/STM-1 trunk modules (TMs) for the Stinger digital subscriber line (DSL) access concentrators offer three options for fiber connections. This gives service providers the flexibility to select the optical technology that best fits their sites' current and future requirements. TMs using single mode optical fiber are available in intermediateor long-reach modes. Long-reach is best suited to sites that need or have growth plans for locating Stingers at remote sites or central offices at distances up to 40 kilometers from the ATM core network. Intermediate-reach single mode fiber extends to 20 kilometers. Cost-effective multimode fiber is an option for connecting to WANs that extend no more than 2 kilometers.

Stinger access concentrators can be subtended or daisy-chained together through their trunk modules. For example, a Stinger RT in an outdoor cabinet can be connected through its TM to a Stinger FS in the central office for traffic aggregation. Traffic from multiple DSL access multiplexers (DSLAMs) can be aggregated through the trunk modules of a single Stinger. This allows Stinger systems to scale to multiple thousands of ports and provides for more efficient utilization of both the central office and remote facilities.

Stinger OC-3c/STM-1 trunk modules are available in either one or two port versions, providing for up to four trunk ports per chassis. Dual-port trunk modules may be configured to use each port independently or for redundant operation. Choosing the redundant feature enables service providers maintain the high network integrity that attracts new customers and retains existing ones. If the second port of a TM is configured for per-port redundant operation, the switchover can either be manual or automatic if the receiving end also supports automatic switchover. If two trunk modules are installed, ports on one module may be designated as backups to ports on the other module. If a primary trunk port should fail, the Stinger control module can command its backup to take over.
