E1 WAN Card
Each E1 card (see Figure 2-24) provides eight E1 span lines, a maximum of four cards (32 T1 spans or 960
DS0 voice channels) are supported in the system.
Each E1 card (see Figure 2-24) provides eight RJ-48 jacks on the rear of the card for connections to a line side
(PBX) or other customer equipment via upstream E1 lines, or to the trunk side (PSTN) via downstream E1
lines. Each E1 line provides 30 B channels and 1 D signaling channel. For each E1 interface, there are two
types of signaling supported: Channel Associated Signaling (CAS) and Common Channel Signaling (CCS).
For the CMS (14 slot), you can insert the E1 card in slots 1 through 4 (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).
