Introduction

For T1 PRI, when the timeslots keyword is not speciﬁed, the pri-group command defaults to

23 B channels with one D channel, with channels 1 through 23 as B channels and channel 24 for the

D channel. The pri-group command creates a logical interface called “interface serial

slot-number-of MIP card /port-number:23.” You use this interface to conﬁgure network protocol

information and DDR information that applies to all the channels of the PRI.

Note For T1 PRI, B channel 1 corresponds to logical serial 0, and D channel 24 corresponds to

logical serial 23.

The following commands conﬁgure a T1 controller positioned in port 0 of slot 2 as an ISDN PRI

using the Extended Super Frame frame type and the Bipolar 8 Zero Substitution line code type:

controller t1 2/0

framing esf

linecode b8zs

pri-group

interface serial 2/0:23

An E1 version of the MIP card can be used as an ISDN PRI for I.421 Euro-ISDN signaling when

used with the ISDN PRI signaling software available in Cisco IOS Software Release 10.3 or later.

The following commands conﬁgure an E1 controller positioned in port 1 of slot 1 as an ISDN PRI

using the CRC4 frame type and the High-Density Bipolar 3 line code type:

controller e1 1/1

framing crc4

linecode hdb3

pri-group

interface serial 1/1:15

!Interface configuration commands go here.

When the pri-group command does not specify the timeslots keyword, the E1 controller defaults to

30 B channels and one D channel, with channels 1 through 15 and 17 through 31 as B channels and

channel 16 for the D channel. The command creates a logical interface called “interface serial

slot-number-of MIP card /port-number:15.” You use this interface to conﬁgure network protocol

information and DDR information that applies to all the channels of the PRI.

Note For E1 PRI, B channel 1 corresponds to serial 0, and D channel 16 corresponds to serial 15.

In Australia, the TS014 PRI switch uses channel 16 as the D channel and channels 1 through 15 and

17 through 30 as B channels.
