NETBuilder II HSS Module Cables


This chapter describes cables used with NETBuilder II HSS modules. The following cables are described:

V.35 Pigtail Cable for HSS V.35/RS-232 Module

This pigtail cable converts the 25-pin connector of the HSS V.35/RS-232 module into a V.35 connector.

Cable ID Number

07-0170-000-01

To connect to the HSS module, you must use a V.35 DTR dial cable on page 6-1 in conjunction with the V.35 pigtail cable.

Figure 8-1 V.35 Pigtail Cable for HSS V.35/RS-232 Module

 


HSS RS-449 3-Port Module Cable

This cable converts the HSS RS-449 3-Port module connector into three RS-449 interfaces. You can use it for dial-up or leased lines.

This cable ships with the module.
