See LTE Mini-PIM Models.

Physical interface for the 4G LTE Mini-PIM

  • The interface name is cl-slot number/0/0 where slot number identifies the slot on the device in which you insert the LTE Mini-PIM. For example, cl-1/0/0.

  • Configurable properties on the physical interface are:

    • A dialer pool to which the physical interface belongs and the priority of the interface in the pool.

    • Profiles for the SIM cards.

    • Radio access technology (automatic, 3G, LTE).

Key deployment

  • Provides wireless WAN support.

  • Operates on 3G and 4G networks.

For hardware specifications for the LTE Mini-PIM, see LTE Mini-Physical Interface Module.

Features Supported on the LTE Mini-PIM

Table 2 describes the key features supported on LTE Mini-PIM.

Table 2: Key Features Supported on LTE Mini-PIM



Automatic switchover between service providers through dual SIMs

Supports dual Subscriber Identity Module (SIM) cards that allow connectivity to two different ISP networks. Automatic switchover provides a failover mechanism when the current active network fails.

Multiple service provider and Access Point Name (APN) profiles

Supports up to 16 profiles configuration for each SIM. The LTE Mini-PIM supports two SIM cards, you can configure a total of 32 profiles and at a time, only single profile is active.

LTE carrier aggregation

Supports increased capacity and network efficiency. Carrier aggregation expands the LTE bandwidth by combining secondary bands.

SIM security functions

Supports security functions such as SIM lock and unlock, and PIN change.

Primary, logical and backup interface with always-on, dial-on-demand, and backup modes

On receiving traffic, the logical dl0 interface enables and places calls through the physical interface in the dialer pool. The dialer interface performs backup and dialer filter functions. You can configure the dialer interface to operate as:

Configuration modes: always-on, dial-on-demand or backup modes. You can configure the Mini-PIM in any one of the modes.

  • Always-on: The Mini-PIM connects to the 3G/4G network after booting. The connection is always maintained.

  • When you configure as primary interface, the LTE Mini-PIM supports both the always-on and dial-on-demand modes.

Over-the-air upgrade for modem firmware

Supports Over-the-air (OTA) firmware upgrade that enables automatic and timely upgrade of modem firmware when new firmware versions are available.

You can enable or disable the OTA upgrade on the LTE Mini-PIM. OTA upgrade is disabled by default.
