Network facilities

Private network facilities

You can order private network facilities from the local telco and other common carriers.
Although you order facilities on a point-to-point basis, the telco must be informed of the overall
planned network, and it generally assists in the design and selection of facilities. The following
facilities can be ordered from the telco:
• 2-wire trunks
- TL 11M/E (E&M Type I signaling)
- TL 12M/E (E&M Type II signaling)
• 4-wire trunks
- TL 31M/E (Type I signaling)
- TL 32M/E (Type II signaling)
Conditioning is the tolerance on frequency response and delay distortion. Several degrees of
conditioning beyond basic line quality are available, including: C1, C2, C3, C4, and D1.
