Provision GR-303 Service
Provision ISDN BRI 4:1 TDM Service to Subscribers
Provision ISDN BRI 4:1 TDM Service to Subscribers
NOTE: The Access Navigator provides GR-303 support for ISDN BRI service using the
4:1 TDM mode, which combines the D (signaling) channels of four BRI connections into
one DS0 channel that is statically connected to the switch. In the 4:1 TDM mode, the switch
uses Call Reference Values (CRVs) to set up ISDN BRI connections.
For 3DS0 transport mode using DCS, see Provisioning ISDN BRI Service on page 9-3.
NOTE: Commands including ds0 <n:ch> require the operator to enter both the DS1
and DS0 channel number or channel range. The DS1 and DS0 numbers are entered with
a colon separating the numbers. For example, the channel list for DS1 #4 and DS0 channel
#8 would be entered as ds0 4:8. The channel list may also contain a range of DS0
channels. For example, DS1 #6 and DS0 channels #1 through #12 would be entered as
ds0 6:1-12. A colon follows the DS1 number, and the beginning and ending DS0
channels are separated by a hyphen.
1. Show current drop DS0 settings with the following command:
show ds0 <n:ch>
Example: show ds0 10:1-2
The show command will display the settings for each DS0 specified. For example, the message for
showing DS1 number 10, DS0 channels 1 and 2 would look similar to the following:
Settings for DS1 10, Channel 1:
Type: GR303
Up/Down: UP
CRV: 1
ISDN: B1
Settings for DS1 10, Channel 2:
Type: GR303
Up/Down: UP
CRV: 1
ISDN: B2
NOTE: In the above message, the channel type can be GR303 (voice or ISDN BRI), or
private crossconnects for VOICE or DATA. Assigning an ISDN BRI to a channel will
automatically change its Type to GR303.
