The Universal Trunk (UTM) is a BNS module that allows the customer to employ more cost-
effective interconnection facilities between Nodes and other BNS product family components
(Remote Shelves and SAM devices). Facilities such as IP, ATM or Frame Relay can be used
rather than traditional leased line services thus permitting the movement of the BNS products
toward the network edge.

The UTM supports an IP infrastructure, which is compatible with an IP-DSU 1 . It also supports a
base protocol layer of HDLC, Frame Relay and AAL5 ATM all at rates up to E1. The transport
layer is implemented using the BNS DDS, SWT, or PQ trunk protocols. UTM trunk interfaces can
be duplexed for higher reliability as well.
Basic IP operations are supported even when the 10BaseT interface is not being used for
transport. These IP applications include ICMP (ping), the Telnet Console, and SNMP.
The Universal Trunk is a companion product to the DT-4000 2 and supports the same trunk
interfaces. Being a firmware based trunk module the UTM may be installed in a SAM64, SAM128,

The IP-DSU allows router (IP) networks to carry both its original traffic and its new BNS-2000/BNS-2000 VCS trunk
traffic simultaneously. The IP-DSU replaces an existing, conventional DSU on each end of the circuit and eliminates the
interconnecting dedicated facility.

The DT-4000 is a product existing in BNS and IP networks simultaneously. It appears to the BNS as a SAM16, but also
supports IP interfaces and significantly higher port speeds. The DT-4000 communicates via Frame Relay, ATM or IP
across the backbone network and becomes a standalone edge device in non-BNS networks
