LTE Mini-Physical Interface Module
The LTE Mini-Physical Interface Module (Mini-PIM) provides wireless WAN support on the SRX300 Series and SRX550 High Memory Services Gateways. The Mini-PIM contains an integrated modem and operates over 3G and 4G networks. The Mini-PIM supports up to two SIM cards and can be installed in any of the Mini-PIM slots on the services gateways.
The Mini-PIM supports the following features:
Automatic switchover between service providers through dual SIMs
Storage support for multiple service provider and access point name (APN) profiles
LTE carrier aggregation
SIM lock and unlock capability
Always-on, dial-on-demand, and backup modes
Over-the-Air upgrade for modem firmware
Figure 1 shows the front panel of the LTE Mini-PIM.

The LTE Mini-PIM ships with a SIM slot cover as shown in Figure 2.

Table 1 lists the components on the front panel of the Mini-PIM.

The Mini-PIM can be configured in three modes:
Always-on—The Mini-PIM connects to the 3G/4G network after booting. The connection is always maintained, as long as there are no network or connectivity problems.
Dial-on-demand—The Mini-PIM initiates a connection when it receives traffic.
Backup—The Mini-PIM connects to the 3G/4G network when the primary connection fails.
The LTE Mini-PIM supports the following wireless standards:
