D19.2-This model transmits synchronous or asynchronous data at "native" DDS rates of 19200, 9600, 4800 or 2400 bps. It responds to DDS diagnostic tests generated by the telephone company, and also features internally controlled tests. It will operate as a limited distance modem from 4.5 to 28 miles, depending on wire size and data rate.
 

D56-This DSU/CSU permits 56 kbps communication in either point-to-point or multipoint networks. An optional adapter cable provides a CCITT V.35 interface for connection to business equipment. The D56 may also be mounted in the Universal Data Shelf multi-modem enclosure.
 

DDS/MR1- This device, which is compliant with AT&T publications 41450 and 62310, provides a choice of data rates (64, 56, 19.2, 9.6, 4.8, 2.4 or 1.2 kbps) and interfaces (EIA232, V.35, EIA-449 or EIA-530). A version is also available that provides a 19.2 kbps DTE rate while using a 56 kbps DDS service. The DDS/MR1 is fully compatible with UDS models D19.2 and D56 units as well as other Bell 500A and 500B units.T1-CSU - This CSU links the user's T1 digital terminating equipment with a T1 network. Includes line equalization and three types of network "keep alive" signaling. One type of "keep alive" signaling included is zero suppression by bipolar substitution (B8ZS) allowing the transmission of data with long strings of zeros while maintaining a sufficient ones density. DTE, network and end-to-end loopback test capabilities are also included.

It provides a choice of EIA or CCITT interfaces and speeds from 300 bps to 64 kbps. AT command and Northern Telecom symbolic keyboard dialing are supported. The unit permits inter-working with Accunet Switched 56 at a data rate of 56 kbps and with ISDN at multiple rates. It is available in an LCD standalone package or configured for Universal Data Shelf mounting.
 

DU100 LS - This unit is a small, desktop sized, standalone unit. It provides the interface between the telephone company's DMS-100 based switched digital data service (Datapath) and the customer's data terminal unit. It will interface with a Northern Telecom DMS type central office switch, an SL-10 or with a Northern Telecom Datapath extension module in a D4 channel bank. It transmits full duplex, asynchronous data at 300 bps to 19.2 kbps when used on intra-switch calls or over a T1 link. The unit provides AT command set compatibility and supports Northern Telecom symbolic keyboard dial.
