EFM Bridge


Patton’s ForeFront 3310P DSLAM is a compact, 1U high, EFM DSLAM in a standalone form factor. This EFM DSLAM aggregates 24 individual copper pair per G.SHDSL.bis. Each copper pair supports up to 5.7 Mbps-15.3 Mbps. Bonding 2, 3, or 4 pair maintains the same reach but multiplyies the maximum symmetrical data rate up to  61.2 Mbps.

The FF3310P EFM DSLAM L2/L3 switch functions offers individual end-user link management for complete network control. Configuring QoS and ToS/DiffServ is the key for controlling each end-user’s link requirements. Traffic is shaped and policed and ToS/DiffServ bits may be re-striped to enforce and to maintain quality service for the end-user.

Proper VLAN creation isolates the end-users’ flows from other customers and also may isolate traffic types within an end-user’s access link. Management of traffic with QoS and VLANs assists in more efficient use of available bandwidth.

VLAN stacking (Q-in-Q) is a technique for the FF3310P to define its own VLANs in the uplink while simultaneously deliver the encapsulated VLANs to the end-users. The clearest example is in port reselling.

With QoS, VLANs, ToS/DiffServ serving to deliver the end-user’s service, ACL is a tool for protecting the end-user’s network from unauthorized access and other types of external probing. Traffic filtering and port blocking, work together in creating the needed protection.

Traffic may be filtered on a per end-user link basis by IP address, MAC address, and port numbers (Layer 4).

EFM is the most efficient service delivery by leveraging Ethernet for carrier-class services to the end-user. Ethernet is a bridging technology; when essential the FF3310P also performs as static routing. VLANs are likewise configurable on a per port basis. Bridged traffic can be tagged and prioritized according to user defined parameters.

The FF3310P DSLAM is easily installed and configured with through the Command Line Interface (CLI) via Telnet, SSH, or local console port, or the graphical, browser-based management via HTTP(S).

EFM bonding over copper wires multiplies the bandwidth of a single twisted-pair link to provide the end-user with a very high-speed uplink and maintain the same distance of the single pair.

EFM is the next-gen replacement for E1/T1 and a cost-effective solution over fiber.
