3. INSTALLATION FOR T1 OST CARDS
3.a Connecting the Rhino T1 Card to T1/E1/PRI
The Rhino OST T1 cards (DS1) interface is an industry-standard RJ48C eight pin connector with its
connections described below. The T1 is usually connected to a Rhino CB24 channel bank or the
telecommunications carrier demarcation point. If the T1 is coming from a Rhino CB24 channel bank, the
T1 cable must be a crossover T1 cable.
Figure 2 shows the pin out for building a T1 crossover cable. This cable can be used to connect two T1
CSU/DSU (i.e. TSU) products in a point-to-point configuration.
