Remote Call Forwarding Under a DMS-100

Overview

This job aid will describe how to build and remove a Remote Call Forwarding (RCF) option to a subscriber's line within the LATA.  This service provides a working telephone number which, when dialed, is remotely forwarded to another Directory Number (DN), thereby giving an appearance of a local presence.  The call forwarding is always activated and is not controlled by the subscriber.  Remote call forwarding is not associated with a physical line.  The subscriber will be responsible for any billable charges associated with terminating the calls, as applicable.

Business Rules

  1. Switch Provisioning Agent who is familiar with a DMS switch, can perform SERVORD, and has their individual login and password.
  2. RCF service will be available where tariffs have been filed.
  3. All switch provisioning steps must be done in sequence of this document.
  4. X = Sample numerical character.
  5. Line Class Code of VLN (Virtual Line) must be assigned in the LINEATTR table to support RCF.
  6. All orders shall be provisioned according to the technical specifications of the contract.
  7. Use this document for any numbers that need the "SIGDATA" option that is necessary for forwarding Operating Company Number (OCN) information on the SS7 Transaction Capabilities Application Part (TCAP) messaging to the terminating customer.  This includes toll-free numbers.

Step One

Research rate centers to identify whether the forwarded DN is local, toll, or long-distance to the local DN.  This document only covers RCF within the LATA.

Step Two

In table LINEATTR (Line Attribute), determine the Line Treatment Group (LTG) and rate area.  Find the appropriate virtual line for your switch and locate the "DFLTRA" and "LTG" fields.

-----------------------------------------------------------------------------------------
>TABLE LINEATTR
>POS 148
148  VLN  NONE  NT  148  0  NILSFC  0  NIL  NIL  00  972_NPRT_148  DALL_L552_57  $
-----------------------------------------------------------------------------------------

Field LTG = 148
Field DFLTRA = DALL_L552_57.  Field DFLTRA is the key into table RATEAREA.

Step Three

In table RATEAREA (Rate Area), determine the Message Rate Service Area (MRSA) using the "DFLTRA" value found in Step Two.

-----------------------------------------------------------------------------------------
>TABLE RATEAREA
>POS DALL_L552_57
DALL_L552_57  DALL  NIL  L552  $
-----------------------------------------------------------------------------------------

Field MRSA = NIL

Step Four

Add the number to the switch using the SERVORD command.  In this example, DN 972-818-0010 will forward to 972-819-2222.

ENTER Y TO CONFIRM, N TO REJECT OR E TO EDIT
>Y
-----------------------------------------------------------------------------------------

Set MAXCALLS to the number of calls which can be forwarded simultaneously.  The customer needs to specify how many paths are necessary per the contract.  The maximum is 48.  Set SIGDATA to "Y" to forward the OCN information to the terminating number.

Step Five

Query the directory number.

RATEAREA: DALL_L552_57
SIGDATA: Y

OPTIONS: NONE
-----------------------------------------------------------------------------------------

Step Six

Make two test calls.

Always make a test call!  One to the forwarded (local) number and one to the RCF number.  They should both terminate at the same place.

Step Seven

Update the order log with the local phone number, forwarded number, LINEATTR table info, translations completed by agent name and number, and whether the test calls were successful.  RCFs are not inventoried in the Access Line Inventory database as there is no hardware office equipment used.

Making Changes to an Existing RCF Directory Number

Once translations are complete, changes such as changing the forwarded number or the number of simultaneous paths may be changed.
