The Cisco Catalyst IR1800 Rugged Series Router now supports the 450MHz category P Long-Term Evolution (LTE) Pluggable Interface Module (PIM), referred to as P-LTE-450. The LTE-450 PIM uses the 450MHz frequency to address LTE use cases primarily targeting utility, public safety, and critical infrastructure maintained by public organizations in Europe and other countries. The module supports only Band 31 and 72, which are the LTE operating frequency bands. Due to hardware limitations, P-LTE-450 is supported only on slot 0/4.

Unlike regular LTE modules, the P-LTE-450 has some differences on the IOS-XE platform. Some of the key differences are:

• IP pass through is on Gigabit Ethernet interfaces rather than cellular interfaces.

• Troubleshooting commands are from the Web user interface of third-party hardware.

Note	Throughout the user documentation, you can see the module referred to as P-LTE-450, the Cisco product name. The module is designed and manufactured by Intelliport, which refers to it as the IPS-701. Both names are present in the documentation.

In P-LTE-450 networks, routers can provide crucial quality metrics through Simple Network Management Protocol (SNMP) Management Information Base (MIB) objects. Specifically, Cisco IR1101 and IR1800 routers equipped with the P-LTE-450 Pluggable Interface Module (PIM) allows you to integrate seamlessly with existing SNMP-based management tools to report their status and quality metrics.

The router identifies the P-LTE-450 module as an Ethernet interface, specifically Gigabit Ethernet 0/1/0, rather than a cellular interface.. For LTE450 0/1/0 radio parameters to be supported through SNMP, a new MIB file named Cisco-LTE450-MIB.my needs to be created. This MIB file includes specific fields to capture radio signal quality metrics.
