ISR G2 Service Performance Engine (SPE)

Integrated Service Router

In this blog, we will take a look at the Services Performance Engine (SPE) supported on the Cisco 3900 series router. The SPE is a modular motherboard design that allows customers to upgrade their routers core functionality without performing a forklift upgrade. The concept is very similar to the modularity that has allowed the following routers and switches to persist for close to or over a decade: •7200 series router input/output (I/O) module •7500 series router – route switch processor (RSP) / versatile interface processor (VIP) •6500 series switch – supervisor module (SUP)/switch fabric module (SFM) The SPE provides the following slots: •Packet Voice DSP Module – third generation (PVDM3) PVDM3 modules replace the PVDM2 modules used in the 2800/3800 ISR routers •Internal Service Module (ISM) The ISM replaces the advanced integration module (AIM) used in the 2800/3800 ISR routers •Enhanced high-speed WAN interface card (EHWIC) EHWIC slots support newer EHWIC cards and the HWIC cards used in the 2800/3800 ISR routers. At the time of this writing, there are only two SPE modules available: 3925 – C3900-SPE100/K9 3945 - C3900-SPE150/K9 In the next blog, I will continue our conversation on new ISR G2 router features.
