The DT-4000 is a multi-access product that can exist in both a BNS-2000/BNS-2000 VCS infrastructure and an IP infrastructure simultaneously. It allows for an incremental transition from your existing network to an IP-based backbone. Thereafter, the DT-4000 acts independently of your BNS-2000/BNS-2000 VCS network.

The DT-4000 approach enables you to have a lower cost and low impact transition as your networks evolve.

The DT-4000 is a multi-access device that can be used as a drop-in replacement for the SAM in any BNS-2000/BNS-2000 VCS network without any IP interconnection. It has 16 asynchronous/synchronous ports with speeds up to 115 Kbps synchronous and 56 Kbps asynchronous. It has a built in IP-GATE and can be used to securely transport IP traffic to a remote LAN off the BNS-2000/BNS-2000 VCS network.The built in IP-DSU function can also be used for IP network access without any BNS-2000/BNS-2000 VCS network connection.

Built-In Flexibility The compact DT-4000 is available in both stand-alone and rack-mount versions to fit your space and configuration requirements. It is available as either a 115V/220V AC or 48V DC powered unit.

As you transition to a new network infrastructure, how can you gain better control over the many legacy network elements that may be incompatible with this new infrastructure? Application and network redesign, interoperability testing, and configuration of new network elements will be interruptive and costly. A part of your solution is built into the DT-4000.

Smart Network Management

The DT-4000 is manageable via StarKeeper II NMS, SNMP manager and local/remote console.

DT-4000 Remote Access and Concentration

The configuration at left is one option of many. However, it does depict some of the interesting interface capabilities of the DT-4000. The DT-4000 on the left communicates with the BNS-2000/ BNS-2000 VCS network via a serial SAMSL/SAMML trunk. It also communicates with IP network end-points via a 10BaseT interface. It can also communicate with any TCP based IP end-point. Note: Both the IP-DSU trunking and standard TCP communications are simultaneously taking place on the 10BaseT interface. Other protocols on the 10BaseT such, as SNMP, Telnet, ARP, etc., are not shown for simplicity of the diagram.
