Digital Connections
A digital T1 (E&M) or E1 (CAS) circuit (trunk) allows the system to connect to
digital network facilities such as a central office (CO) switch. Digital connections
between a DEFINITY® switch and the system can be through PRI, T1 (E&M), E1
(CAS), line-side T1, or line-side E1.
E1 or LSE1 reduces the required hardware to only one E1 circuit card (and part
of an SP or SSP circuit card). T1 or LST1 requires one T1 circuit card (and part of
an SP or SSP circuit card) per 24 channels of digital service. Two T1 circuit cards
and one SP circuit card provides 48 voice channels.
The AYC3B and AYC11 circuit cards are used only for T1 services.The AYC21
circuit card may be used for either E1 or T1 services.
Central Office Connection—T1 Circuit Cards
The system supports three T1/E1 circuit cards.
