Avaya CS 1000: Defining Calling Line Identification Numbers

The Calling Line Identification (CLID) feature allows a CS1000 or Meridian 1 telephone to send a caller's telephone number to the called party. The presentation of CLID information is of particular importance when the caller dials an emergency number. This white paper describes a two-part process used to define CLID information for both emergency and non-emergency calls. The first part of the process involves defining the number(s) that will be sent to the called party. This is commonly referred to as defining a CLID entry. The second part of the process involves assigning the CLID entry to an analog telephone or to a key on a digital or IP telephone.

A CLID entry can be defined using the Element Manager interface. To define the CLID entry, do the following:

1. Select Customers from the Element Manager tree.

2. At the Customers page, click on the appropriate customer number.

3. At the Customer Details page, click on ISDN and ESN Networking.

4. At the ISDN and ESN Networking page, click on Calling Line Identification Entries.

5. At the Calling Line Identification Entries page, click on Add.

6. At the New Calling Line Identification page, define the following parameters:

Entry Id = the number of the CLID entry you are defining
National Code, 1-6 digits = the area code that should be sent to the called party
Local Code, 1-12 digits = the local prefix that should be sent to the called party
Home Location Code, 1-7 digits = the home location code that should be sent to the called party
Use DN as DID =

- YES means that you want to precede the DN of the active DN key with the digits defined in the National Code and Local Code fields
- NO means that only the digits defined in the National Code and Local Code fields should be sent to the called party
- SEARCH means that you want the system to search the DN keys of the telephone (beginning with key 0) and use the first CLID entry that has this field set to "yes"

Emergency Local Code, 1-12 digits = the local prefix that should be sent to the called party when an Emergency Services Directory Number (ESDN) is dialed (The ESDN is defined as part of the Emergency Services Access feature available on a Meridian 1 or CS1000 system.)
Home national number for emergency services access calls = a check means that the number defined in the National Code field should precede the number defined in the Emergency Local Code field when an Emergency Services Directory Number (ESDN) is dialed (the ESDN is defined as part of the Emergency Services Access feature available on a Meridian 1 or CS1000 system)
Append the originating directory number for Emergency Services Access calls = a check means that the DN of the active DN key should be added to the number defined in the Emergency Local Code field (Emergency Services Access is a feature available on a Meridian 1 or CS1000 system)

7. Scroll to the bottom of the page and click on Save.

A CLID entry can also be defined using the system's command line interface. To define the CLID entry, do the following:

1. Log into the system.

2. Access LD 15 and respond to the prompts listed in the example that follows:

>LD 15
REQ: chg Change
TYPE: net Networking
CUST 0 Customer Number
CLID yes Allow Calling Line Identification Option

ENTRY 1 CLID Entry To Be Configured
HNTN 214 Nati onal Code, 1-6 digits = the area code that should be sent to the called party
ESA_CLCL 250 Emerg ency Local Code, 1 digits + the local prefix that should be sent to the called party when an Emergency Services Directory Number (ESDN) is dialed (the ESDN is defined as part of the Emergency Services Access feature available in a Meridian 1 or CS1000 system)
ESA_INHN yes Hom e national number for emergency services access calls = "yes" means that the number defined at the HNTN prompt should precede the number defined at the ESA_HLCL prompt when an Emergency Services Directory Number (ESDN) is dialed (The ESDN is defined as part of the Emergency Services Access feature available on a Meridian 1 or CS1000 system.)
ESA_APDN yes Appe nd the originating directory number for Emergency Services Access calls = "yes" means that the DN of the active DN key should be added to the number defined at the ESA_HLCL prompt (Emergency Services Access is a feature available on a Meridian 1 or CS1000 system.)
HLCL 250 Local Code, 1-12 digits = the local prefix that should be sent to the called party
DIDN yes Use DN as DID = YES means that you want to precede the DN of the active DN key with the digits defined at the HNTN and HLCL prompts; NO means that only the digits defined at the HNTN and HLCL prompts should be sent to the called party; SEARCH means that you want the system to search the DN keys of the telephone (beginning with key 0) and use the first CLID entry that has this field set to "yes"
