On HP A-MSR50 Series routers, which component holds the slots for Voice Processor Modules (VPMs)?

Question

Options

• Athe Main Processor Module or Main Processing Unit F (MPUF)
• Bthe High-Performance Processor Module or Main Processing Unit-G2 (MPU-G2)
• Cthe Multi-Service Module or Multi-Service Card A (MSCA)
• Dthe Flexible Interface Card (FIC)

• A
  6% (1)
• B
  6% (1)
• C
  72% (13)
• D
  17% (3)

Explanation

The MSCA includes the following: Four Voice Processing Module (VPM) slots One or more VPMs are required when the A- MSR 50 Series router supports digital voice traffic. A VPM provides digital signal processing (DSP), coderdecoder (CODEC) functions, echo cancellation, and noise suppression for multiple digital voice channels. Customers can install 8-channel, 16- channel, 24channel, and 32-channel modules. One Voice Co-Processing Module (VCPM) slot A VCPM is also required for digital voice traffic. This module handles the processing for voice traffic, setting up the Time Division Multiplex (TDM) exchanges for each data voice channel. Two Enhanced Services Module (ESM) slots An ESM enhances performance when an A-MSR 50 Series router implements an IPsec VPN. Instead of implementing encryption and decryption in the software, which can decrease performance, the router offloads the encryption and decryption of packets to the ESM. Customers can choose from two types of ESM: Advanced Network Data Encryption ESM Standard Network Data Encryption ESM The MSCB includes: One VCPM slot Two ESM slots These slots accept the same modules as those on the MSCA.
