3.2.7 CR8N
Introduction
In Release 1.0 (SMR-Q) and Release 2.2 (SMR-H) and later, you can install CR8N (Code Receiver) in any slot in all OfficePro cabinets. The board cannot be used in Release 1.1, which must first be upgraded to Release 2.2 software.
The CR8N board is required for:
 |
A high outgoing traffic load and a large number of analog subscribers exist. |
 |
A Hicom Phonemail system with more than six ports and the automatic attendant function is connected. |
 |
An external automatic attendant is being used as a virtual attendant and the system has a large number of analog trunks. |
In these cases, the six code receivers (for tone dialing on analog telephones) that are already present in the system on the CBMOD are not sufficient. Adding a CR8N board provides another eight code receivers and eight code transmitters. Up to two CR8Ns can be installed in each system. A CR8N board and a CR8 board (S30810-Q2513-X) cannot be used in the same system simultaneously.
You can also install or remove a CR8N board during operation. If you remove it while the system is in the operating state, you risk interrupting DTMF signal processing. It is always recommended that you remove or install the board only while the system is switched off.
Note the following recommendations for using the CR8N board if a Hicom Phonemail system, voice mail system, or automatic attendant is connected:
 |
Up to 8 ports: No CR8N board required. |
 |
9 to 24 ports: One CR8N board required. |
 |
Over 24 ports: Two CR8N boards required. |
These are general recommendations only. In some cases, a CR8N board may already be required for six ports under extreme load conditions.
