1
Use a TN767E (or later) DS1 or a TN464GP DS1/E1 circuit pack for a signaling link and up to 23
ISDN — PRI Trunk Group members.
2
Install a Tone-Clock circuit pack to provide synchronization for the DS1 circuit pack.
3
If using a TN464GP, then packet bus support has not been added, requiring greater than 4 PRI
signaling groups, see
Add Packet Bus Support
on page 588 for installation of additional circuit
packs for packet bus support.
As an option to the TN768 or TN2182B Tone-Clock, a TN780 Tone-Clock (installed in the PPN) can
interface external Stratum 3 synchronization for DS1.
