The ATT ATTTL88002 is a DECT 6.0 accessory handset designed to expand two-line answering systems with additional cordless coverage. It operates on the 1.9 GHz DECT 6.0 frequency band, delivering long-range wireless performance and reduced interference compared to older cordless standards. The backlit LCD displays caller name, number, time, and date, and stores up to 50 Caller ID entries for quick reference. A built-in speakerphone and noise-filtering technology maintain audio clarity in busy environments. This handset is intended for office and light commercial settings where multi-handset phone coverage is required without running additional wiring.
The ATTTL88002 is used in residential and small commercial environments that already run an ATT two-line answering system. It adds a supplementary handset station without requiring a new base unit, making it practical for expanding coverage across multiple rooms or work areas. Dual Caller ID and Call Waiting support allow the handset to handle simultaneous incoming call notifications on both lines. The high-contrast black text on white LCD background supports readability in varying light conditions.
Compatible with ATT two-line answering systems that support DECT 6.0 accessory handset registration.
Registration of the accessory handset to an existing ATT base unit is required before use and should follow the base unit pairing procedure outlined in the system documentation. No telephone wiring or low-voltage cabling is required at the handset location. Ensure the base unit is powered and operational before initiating the pairing sequence. This handset does not function as a standalone unit without a compatible ATT base system.
