1 Chapter 14 Configuring T1/E1 and ISDN PRI Options

2 Objectives Upon completion of this chapter, you will be able to perform the following tasks: Identify channelized T1 and E1 configuration commands Identify ISDN PRI configuration commands

3 Configuring T1 and E1

4 Channelized T1/E1 Overview  DS-0 framing for a single 64-kbps channel  DS-1 framing for a single Mbps T1 or Mbps E1 T1 MUX 24 Subchannels 30 Subchannels E1 MUX

5 Channelized T1/E1 Overview Public Data Network Private Data Network Public Data Network 64 kbps Subshannels kbps Subshannels kbps T1/E1 MUX Port 0 Port 1 MIP MultiChannel interface Processor (Channelized T1/E1) Cisco kbps FSIP 4-port Fast Serial Interface Processor Cisco 7000 CSU/DSU Becomes

6 Channelized T1/E1 Configuration Router (config) # Controller [t1 | e1] [slot/port | number] Configures T1 or E1 controller and enters controller configuration mode Router (config-controller) # Channel-group number timeslots range speed { 48 | 56 | 64 } Specifies the channel group (subchannel) associated with each time slot

7 Channelized T1 Configuration Router (config-controler) # framing { sf | esf }  Defines the framing type required for a fractional T1 data line Router (config-controller) # linecode { ami | b8zs } Specifies the line code type required for communication with the service provider Router (config-controller) # clock source { line | internal } Sets the clock source

8 MultiChannel Interface Processor Channelized T1 Configuration Example T1 Line (Port 1) (Slot 4) Cisco 7000 controller t1 4/1 framing esf line code b8zs clock source line channel-group 0 timeslots 1 channel-group 8 timeslots 6-11 ! Interface serial 4/1:0 ip address encapsulation ppp ! Interface serial 4/1:8 ip address controller t1 4/1 framing esf line code b8zs clock source line channel-group 0 timeslots 1 channel-group 8 timeslots 6-11 ! Interface serial 4/1:0 ip address encapsulation ppp ! Interface serial 4/1:8 ip address

9 Channelized E1 Configuration Router (config-controller) # framing { crc4 | no-crc4 } [ australia ] Defines the framing type required for a fractional E1 data line Router (config-controller) # linecode { ami | hdb3 } Specifies the line-code type required for communication with the service provider

10 MultiChannel Interface Processor Channelized E1 Configuration Example E1 Line (Port 1) (Slot 4) Cisco 7000 controller e1 4/1 framing crc4 line code hdb3 clock source line channel-group 0 timeslots 1 channel-group 8 timeslots 5,7,12-15,28 ! Interface serial 4/1:0 ip address encapsulation ppp ! Interface serial 4/1:8 ip address controller e1 4/1 framing crc4 line code hdb3 clock source line channel-group 0 timeslots 1 channel-group 8 timeslots 5,7,12-15,28 ! Interface serial 4/1:0 ip address encapsulation ppp ! Interface serial 4/1:8 ip address

11 Configuring Primary Rate Interface

12 ISDN PRI Is 23B+D (or 30B+D) ISDN Cisco 7000 T1/E1 link 64-kbps D channel for B channel-call setup All PRI channels are 64 kbps (DS-0) 23/30 B D InterfaceB ChannelsWhere used T1 PRI 23North America and Japan E1 PRI 30Europe and rest of the World InterfaceB ChannelsWhere used T1 PRI 23North America and Japan E1 PRI 30Europe and rest of the World

13 Configuring for PRI  Select PRI switch type  Specify T1/E1 controller, framing and line coding for the facility  Set PRI group time slot for T1/E1 and indicate speed used  Specify the interface on the router that you will configure for DDR CSU/DSU ISDN

14 ISDN PRI Configuration Router (config) # isdn switch-type primary rate switch type Specifies ISDN PRI service switch type Router (config) # controller { t1 | e1 } slot/port | number Configures T1/E1 controller

15 T1/E1 Controller Options for PRI Router (config-controller) # framing { esf | crc4 } Selects the framing type on the router processor or module to interface ISDN PRI service Router (config-controller) # linecode { b8zs | hdb3 } Selects the line code type on the router processor or module to interface ISDN PRI service

16 ISDN PRI Configuration Router (config-controller) # pri-goup [ timeslot range ] Specifies ISDN PRI on the router’s channelized T1/E1 card and sets appropriate speed Router (config) # interface serial slot/port | number: { 23 | 15 }

17 PRI Configuration Example CSU/DSU ISDN isdn switch-type primary-4ess ! controller t1 2/0 pri-group timeslots 1-23 framing esf linecode b8zs ! interface serial 2/0:23 !(set ip address, dialer, provider config statements) ip address isdn switch-type primary-4ess ! controller t1 2/0 pri-group timeslots 1-23 framing esf linecode b8zs ! interface serial 2/0:23 !(set ip address, dialer, provider config statements) ip address Cisco 7500 T1 4ESS
