NOTE: J-Web does not currently support configuration of GSM ExpressCards.
Task 6: Connect the External Antenna
The supplied multi-band external antenna allows superior reception of wireless signals
and reduces possible radio frequency noise generated by electrical/electronic
components around the SRX210 Services Gateway. The antenna has a magnetic mount,
so it must be placed far away from radio frequency noise sources including network
components.
To connect the external antenna:
1. Connect the end of the external antenna cable to the antenna port of the 3G
ExpressCard.
2. Push the connector firmly until it is secure. The antenna is now ready to be used.
Configuring the 3G Expresscard as a Failover/Backup Link
The figure below illustrates a basic setup for 3G connectivity for two branch offices.
Branch Office A has a T1 leased line as the primary WAN link and a 3G connection as
the failover link. Branch Office B uses the 3G connection as the primary WAN link.
Task 1: Configure the Dialer Interface and 3G ExpressCard Interface
To configure the dialer interface:
[Edit]
user@host# set interfaces dl0 description 3g-wireless encapsulation ppp
unit 0 dialer-options pool 1 dial-string 14691
[Edit]
user@host# set interfaces dl0 unit 0 family inet inet negotiate-address
To configure the dialer pool for the 3G ExpressCard interface:
[Edit]
user@host# set interfaces cl-0/0/8 dialer-options pool 1 priority 25
To configure modem options for the 3G ExpressCard interface:
[Edit]
user@host# set interfaces cl-0/0/8 modem-options init-command-string
ATE0
To configure a GSM profile for the GSM 3G ExpressCard interface, navigate to the
top level in the hierarchy:
[Edit]
user@host# request modem wireless gsm create-profile profile-id 1-16
sip-user-id username sip-password password access-point-name ap-name
authentication-method pap/chap
To designate the GSM profile you configured as the active profile:
[Edit]
user@host# set interfaces cl-0/0/8 cellular-options gsm-options
select-profile profile-id 1-16
Task 2: Check for Authentication from the Service Provider and Configure
One of Two Available Options
To configure Password Authentication Profile (PAP) on the dialer interface:
[Edit]
user@host# set interfaces dl0.0 ppp-options pap default-password
password
[Edit]
user@host# set interfaces dl0.0 ppp-options pap local-name username
[Edit]
user@host# set interfaces dl0.0 ppp-options pap passive
NOTE: The CDMA ExpressCard should be activated before it is inserted into the
SRX210 Services Gateway. The SRX210 Services Gateway support for ExpressCard
activation is not available in Junos OS Release 10.2.
