Chapter 4: CSMIM-T1 Parameters

map

This T-1 parameter controls the mapping of the modems to the T1 Drop and Insert Interface (T1DII) and the T1 Network Interface (T1NI) DS0 slots/channels. The modems can be mapped to any unoccupied slot on the T1NI or the T1DII. The T1NI and the T1DII can be mapped to each other on channels that are not occupied by modems. Information flowing between the T1NI and a modem and the T1DII and a modem flows as voice, not data. Table 4-6 lists the options that are used with the map parameter.

Table 4-6 Options for the Map Parameter

Option	Description
map_val modem_number	These options map an interface to a modem.
	The map_val option defines the interface as:
	ds for the T1 Network Interface (the DS0
	channel).
	di for the Drop/Insert Interface.
	The modem_number option must be specified.
	The modem_number value is a number from 1 to
	24.
map_val	The map_val option by itself maps the T1
	Network Interface to the Drop/Insert Interface.
	The map_val defines the type of channel as
	data, voice, or unused.

ring

This T-1 parameter is used to provide the audible ring to the central office for incoming calls. The default is Y, and the audible ring is sent to the central office. This parameter is used with wink_start and immediate_start protocols only.
