Actually, until 800 MHz Rebanding takes place in Southern California, the 5 International Mutual Aid channels (hence the "I") are still known as I-Call and I-TACs 1-4.
Once the channels have changed frequencies, the names will become 8CALL90 and 8TAC91 through 8TAC94, in accordance with the adopted ANS Standard Channel Naming document.
