Parameters that define and apply to channels (time slots). These go inside interface markers.
channel_group_begin | Marks the beginning of a group of channels. All parameters following this label apply |
| only to this channel group until channel_group_end is reached. |
channels | The number of channels in this channel group is defined. The value can be first- |
| last or channel_numberchannel_numberchannel_number etc. |
channel_group_end | Marks the end of a group of channels. See comments for channel_group_begin above |
| FIG. 4.5 CHANNEL PARAMETERS |
Parameters that define and apply to logical links. These go inside interface markers.
interfn_1_begin | Marks the beginning of the parameters for logical link 1. PRI allows 23 (T1) or 30 (E1) |
| channels whereas CAS allows 24 (T1) or 30 (E1) channels. |
connection_type | Indicates whether channel will be used for |
phone_num | Phone number assigned to the channel. The maximum number of characters is 30. |
dsp_profile_id | Specifies the DSP profile to be used for analog calls. 5 profiles are possible. |
interfn_1_end | Marks the end of the parameters for logical link 1. |

The default values and sample configurations are described later in this chapter in the examples section. The firmware should be loaded with the command:
pc400load
which will load the file in /usr/local/lib/pc400.bin.
This configuration file should be loaded into the board’s memory with the command:
pc400util -p
The options of this command are given in appendix A.
STEP THREE
Edit one of the rc files (e.g. /etc/rc.d/rc.local) to include a call to the PC400´s firmware loader and con- figuration utility (so that the firmware and current configuration are loaded on boot):
