.Install ISDN converters and adapters
This section provides information on ISDN converters and adapters that are sometimes necessary when
connecting to coaxial facilities in either a multicarrier cabinet or a single carrier cabinet.
Connections include:
• Integated Services Data Network Primary Rate Interface (ISDN-PRI) to Direct Access Secondary
Storage (DASS)
• PRI to Digital Private Network Signaling System (DPNSS)
• PRI to ISDN Basic Rate Interface (ISDN-BRI)
Converter circuit packs known as common channel signaling converter (CCSC), types 1 and 2.
Converters for single-carrier cabinets
PRI-to-DASS and PRI-to-DPNSS converters
Figure 320 shows typical connections from the CCSC-1 PRI-to-DASS converter or the CCSC-2 PRI-to-
DPNSS converters to the coaxial facility.
