HSSI to V.35, X.21, RS422/530 CONVERTER
V.35 cable &
V.35 cable gender mender
M/34 to M/34 and V.35-M/34 cable to DB25
V.35 to HSSI Interface Converter
Convert V.35 to HighSpeed Serial Interface (HSSI) at speeds up to 10
Key Features for the
Model 2040, V.35 to
a 2040 can convert HSSI to V.35 or RS422 or RS232 X.25
note DCE and DTE pin out on interfaces
Interface a DTE or a DCE?
HSSI (High-Speed Serial Interface) devices can now bi-directionally communicate with V35 devices at speeds up to 10 Mbps. The V35- HSSI Interface Converter supports all HSSI co-directional timing patterns, two loopback modes (local line and remote line), plus data and control signals.
Two versions of the Interface Converter are available. The 2040MT/MC lets a V.35 DTE device communicate with a HSSI DCE device. The 2040MC/MT lets a V.35 DCE device communicate with a HSSI DTE device. Both versions are equipped with a male M/34 connector on the converter end, and a male HD-50 on the end of a 6 foot (1.8m) cable (other connector genders and cable lengths are available on a custom basis). Power is supplied to the Model 2040 by an external AC transformer
Both STANDARD versions are equipped with a male M/34 connector on the converter end, and a male HD50 on the end of a 6-foot (1.8-m) cable. Power is supplied by an external AC power supply.

Application part number
Communications V.35 DCE device to HSSI DTE data device.
M/34 DTE/HD50 DCE
Communications HSSI DCE device to V.35 DTE data device.
M/34 DCE to HD50 DTE
When selecting converters a DTE must connect to a DCE or a DCE must connect to a DTE.
If you have a CSU V.35 to a Router HSSI - the CSU will be DCE (which will connect to the converter DTE) and the router will be a DTE (which will connect to the converter DCE)
The Model 2040MC-MT is designed to connect a V.35 or RS-422 DTE device to an HSSI DCE device. In this application, the M/34 (V.35) and HD-50 (HSSI) male connectors of the Model 2040MC-MT may connect directly to their respective equipment ports, or they may connect via a short "straight-through" cable. Figure 7 below Illustrates the proper connection of the Model 2040MC-MT.
The Model 2040MT-MC is designed to connect a V.35 or RS-422* DCE device to an HSSI DTE device. In this application, the M/34 (V.35) and HD-50 (HSSI) male connectors of the Model 2040MT-MC may connect directly to their respective equipment ports, or they may connect via a short "straight-through" cable. Figure 8 below illustrates the proper connection of the Model 2040MT-MC.
(NOTE the 2042MC-MT/UI has a DCE connector of a DB25 male not a DB15 as shown above)
