Need PVDM when use HWIC-2CE1T1-PRI for leased line?

[Sindibade 78]

Hello,

We plan migrate an old existing WAN architecture based on legacy data serial links. These links will be consolidated on a E1 channalized card.

My question :

Is the HWIC-2CE1T1-PRI need a PDVM DSP ressources on router  to oparate for data leased lines or no?

The VWIC3-1MFT-T1/E1 will be used for the backup dial in ISDN connexions? this type of cards a PVDM DSP ressources for data connexions or no?

ISR router are 2911.

1. no, use VWIC instead. there are other types also.

2. for ISDN connections, use  HWIC-xCE1T1-PRI

The PDVM is necessary when we  use the E1 channalized PRI for data leased line? what is the impact?

As answered above already: no PVDM is necessary.

Thank you for the nice rating and good luck!
