We're running Unity Connection 7.1.3 and we want to integrate that with an NEC 2400 PIX. We have purchased a TIMG unit. Question is very simple: how do I configure the T1 on the NEC? Will it be a CAS using E&M? What about framing and line coding? ESF and B8ZS? Any other settings that I'd need to know? My customer is requesting these specific information and I want to provide them with correct answers. Thank you.
