Chapter 2: Hardware Components

T1 WAN Card

Each T1 card (see Figure 2-22)provides eight T1 span lines, a maximum of four cards (32 T1 spans or 768 DS0 voice channels) are supported in the system.

Each T1 card provides eight RJ-48 jacks on the rear of the card for connections to a line side (PBX) via upstream T1 lines or to the trunk side (PSTN) via downstream T1 lines. Each T1 line provides 24 channels. For each T1 interface, there are two types of signaling supported: Channel Associated Signaling (CAS) and Common Channel Signaling (CCS). For T1 using CAS, channels 1-24 are available; for T1 using CCS, chan- nels 1-23 are available.

For the CMS (14 slot), you can insert the T1 card in any one of the four left most slots (when facing the front of the chassis).

A crossover cable is required when connecting to a Line side (PBX) interface (when supplied by Quintum, this is a red RJ-45 cable). A straight cable is required when connecting to the Trunk side (PSTN) interface (when supplied by Quintum, this is a green RJ-45 cable).

Span LEDs. The T1 card contains eight Span Status LEDs, viewable from the front of the chassis, to provide a high level indication of the system operational mode and chassis activity, including alarm activity. Each LED relates to one line on the rear of the T1 WAN card. For example, Span Status 1 indicates the operational activity of port 1 on the rear of the T1 WAN card. If all LEDs are lit green, the lines are operating properly.
