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 Lucent ESF T1 CSU, or
integrated
for
the 120A1 CSU Module or the 401A T1 Sync Spliltter. Answering
integrated
will
cause additional fields to be displayed for administering the Enhanced
Integrated CSU Module.
E1 Sync-Splitter?
is set to
y
if a 402A or 403A E1 Sync
splitter is used to provide timing to an ATM switch. 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

DS1/CEPT/ISDN-PRI Reference
, 555-025-107.
Two option jumpers located on the side of the TN464C/D circuit pack must be
installed correctly. The figures on the following page shows how to configure the
circuit pack for 24-channel or 32-channel DS1, and for 75*W (coaxial) or 120*W
trunk connections. The channel selection must match the parameters
administered on the corresponding DS1 Circuit Pack Form. (US applications use
24 Channels.)
