Parameter Descriptions
CSMIM-T1 Hardware Installation Guide 4-11
sigproto
This T-1 parameter is used to specify the inbound and outbound signaling
protocols supported by each T-1 channel (DS0). Each channel supports an
inbound protocol and an outbound protocol. Both protocols must be
specified even if they are the same. If the protocol pair is invalid, it is
rejected with an error message. For inbound-only channels, the outbound
protocol must be set to none. For outbound-only channels the inbound
protocol must be set to none.
t1_info
This T-1 parameter stores installation information from the service
provider, such as a telephone number to call should the network go down.
This parameter is limited to a 128-byte string of printable ASCII
characters.
tdi_distance
This T-1 parameter defines the distance, in feet, of the cable that runs
from the T1DII to the Private Branch Exchange (PBX) or other
equipment. The parameter setting is an integer from 1 to 655. The default
setting is 0.
tdi_framing
This T-1 parameter controls which superframe format is used on the T1
Drop/Insert Interface. The parameter settings are d4 (superframe) and esf
(extended superframe). The default setting is esf. The value for
tdi_framing may or may not be the same as tni_framing.
tdi_line_code
This T-1 parameter selects the line code to be used on the T1 Drop/Insert
Interface (T1DII). The device connected to the T1DII determines which
line code to use. The parameter settings are ami and b8zs. The default
setting is b8zs.
tni_circuit_id
This T-1 parameter stores the T-1 circuit identifier string. The T-1 circuit
identifier string comes from the service provider and is used for customer
service calls. The parameter setting is a string of up to 128 characters. The
default setting is the null string.
