Product Description 1-3
Product
Description
The HiPer Digital Signal Processor (DSP) Network Application Card (NAC)
comes in two varieties: one that supports T1 applications such as
Channelized T1 and T1/PRI, and one that supports E1 applications such as
E1/PRI and E1/CAS. The HiPer DSP for T1 applications contains 24
modems while the E1 version has 30.
Together with the HiPer DSP T1/E1 Network Interface Card (NIC), the
HiPer DSP NAC terminates an entire T1 or E1 span, which greatly
increases the channel capacity of the Total Control chassis.
Product
Compatibility
The HiPer DSP NAC is compatible with the HiPer DSP T1/E1 NIC.

2INSTALLATION
This chapter contains HiPer Digital Signal Network (DSP) Network
Application Card (NAC) installation information.
Installation Tools To install this NAC in the Total Control chassis, you need a #2 Phillips and
flat-head screwdriver.
Installation
Procedure
To install this NAC:
ESD: To reduce the risk of electrostatic discharge (ESD), take proper
grounding precautions before handling the NAC.
1Install the Network Interface Card (NIC) corresponding to this NAC.
Refer to the NIC’s Getting Started Guide for more information.

2-2 CHAPTER 2: INSTALLATION
2Configure the NAC via the DIP switches.

Installation Procedure 2-3
Install the NAC with or without power applied to the chassis.
3Select a slot at the front of the Total Control chassis for installing the
NAC.
Install this NAC in slot(s): 1–17
For managed chassis, slot 17 is reserved for the Network Management
Card (NMC) NAC.
4Use a #2 Phillips screwdriver to remove the safety panel covering this slot.

2-4 CHAPTER 2: INSTALLATION
5Insert the NAC between the slot’s upper and lower card guides.
6Holding the tabs perpendicular to the NAC’s front panel, slide the NAC
into the chassis, until the front of the NAC is flush with the chassis.
Push the tabs toward each other to secure the NAC.

Installation Procedure 2-5
7Use a flat-head screwdriver to tighten the screws on the front panel.
8Cover any unused chassis slots with safety panels.
9Apply power to the chassis, if power is not already applied.
10 After the NAC boots, verify that the RN/FL (run/fail) LED is green.
■If the RN/FL LED does not light, is solid red or flashing
red, there is an error. Refer to the Trouble Clearing section
for more information.
■If the RN/FL LED is green, continue configuring the HiPer
DSP NAC. Refer to the Product Reference for configuration
information.

ATROUBLE CLEARING AND
TECHNICAL SPECIFICATIONS

Loss of Signal Red The received T1 or E1 signal has been lost. The HiPer
DSP declares a red alarm and sends a yellow alarm to
the remote end.
Out of Frame Red The received T1 or E1 framing has been lost and the
framed payload can no longer be received. The HiPer
DSP declares a red alarm and sends a yellow alarm to
the remote end.
Unframed all

Blue The remote end is sending out an all ones signal. This is
usually done when the remote end can not send out a
