Circuit Pack Administration and Options
The DS1 configuration for each circuit pack is administered on the DS1 Circuit
Pack form.
Bit Rate is set to 1.544 Mbps for 24-channel systems, and 2.048
Mbps for 32-channel systems.
Country Protocol is used to drive layer 3 protocol
decisions based on PRI specifications specific to a given country (not those
related to specific features). This Country Protocol is independent of the
Country
parameter administered on the country-options system-parameters form.
Different UDS1 circuit packs may be administered with different Country
Protocols, allowing the switch to act as a gateway between two incompatible
ISDN-PRI implementations (for example, between two different countries). US
systems use country protocol 1.
Near-End CSU Type is set to other for no CSU
installed,
or for an external CSU such as an AT&T ESF T1 CSU, or integrated for
the 120A1 CSU Module. Answering
integrated will cause additional fields to be
displayed for administering the Enhanced Integrated CSU Module. In addition to
the above there are numerous other fields defining such parameters as framing
modes, line coding companding mode and so on. For details, see

Figure 10-93
through Figure 10-95 show how to configure the circuit pack for
24-channel or 32-channel DS1. The channel selection must match the
parameters administered on the corresponding DS1 Circuit Pack Form. (US
applications use 24 Channels.)
