ISR4000 Series

Restrictions

Cards NIM can only be used on routers Cisco 4321 and 4431 series. Multiflex modules have the form of digital processors that transmit signals using a voice data packet.. PVDM2 and PVDM3s no longer supported.

How synchronization works?

In routers 4331 NIM used for voice and other applications. In speech T1/E1 synchronized with one source. If there is any difference in the clock, it may cause flaps in the interface. When applying applications and new data, all ports have independent type timing. It is supported in automatic mode, subject to configuration at the global level.. If the slot is not entered, the command will be called ineffective. Applied Source Priority Controller is used to control timing.

To check the network performance on the router 4351, use a modular device. It can also be used to find out if a backplane is available..

Advantages

They can be designated as:

• Processor architecture, multi-core.
• Traffic divides data, and services allow you to achieve uniform operation of the device.
• The presence of a large number of modules.
• A wide range of services taking place in one device - application control and firewall creation, VPN, voice messaging.
• Platform visualization and integration of services into the infrastructure.
