Hi,
Service Module Slots are used for router modules that run specific services that could be either Cisco proprietory or third party applications. These modules have their own processors, memory etc and don't use any of the router's resources.
The new Gen2 ISR's use the Enhanced version of SFP and copper GE interfaces to provide connectivity for high speed uplinks.
Please have a look at the link below for more information. On this page have a look a the link for Cisco Supported and Unsupported Modules for Integrated Services Routers. This document provides some very useful information for the 3900 series.

I hope this helps.

Network Module slot is different than the on board WIC/HWIC slots. As SM,NM's have the specific hardware to support some services like onboard PVDM for voice support. Your E1 interface can go either on NM'S module or onboard WIC slot depending upon which E1 module you have selected.these voice E1 modules are supported both on NM'S and WIC slots.

Hi,
The 4 port voice card will be installed in the NM slot at the back of the router.
An Integrated Service Modules (ISMs) and Packet Voice and Video Digital Signal Processor Module (PVDM) are installed on internal motherboard slots in the router.
ISM Installation
PVDM Installation

HI
From Previous conversation I am understand EHWIC and Service Module Card and now understand NM is different module. One port or two port E1 installed in WIC slot.
My question is: In Product Reference Guide I have found
3945E --- Have 3 EHWIC , 4 Service Module, 0 ISM Module and 3 PVDM , 3 DSP SLot
3925 --- Have 4 EHWIC , 2 Service Module , 1 ISM Module and 4 PVDM , 4 DSP Slot
Question:
1. What is benefit of ISM ? when customer need ISM ? why not ISM slot in 3945E ?
2. By default PVDM slot is empty ? if customer chhose for Voice license then how many PVDM come with slot ?
3. 3945 E and 3925 have 3 and 4 DSP Slots by default how many DSP comes with and if customer want more DSP then its load separetly ?
