# Allow Broadcasting to a Broadcast Mailbox

Use this procedure to allow a broadcast mailbox to send a message to another broadcast mailbox, which can rebroadcast the message.

1. Customize an FCOS to include some or all of the following feature bits, as applicable:

   - 174 (define broadcast greeting mailbox)

   - 175 (receive broadcast greeting)

   - 178 (define broadcast name mailbox)

   - 179 (receive broadcast name)

2. Assign the number 1 to the distribution list in the receiving broadcast mailbox.

3. Include the receiving broadcast mailbox in Distribution List 1 of the sending broadcast mailbox.

4. Configure the receiving broadcast mailbox with the applicable FCOS, LCOS, and GCOS the same as for any distribution list message receiving.
