RAD OP-4E1L/B/ST13L

Optimux-4E1L Four E1 Channel Multiplexer • Optimux-4E1L transmits each of the E1 channels independently, such that the clock of each E1 channel is independent of the clock of any other E1 channel. • The E1 interface can be 75Ω unbalanced or 120Ω balanced (see Ordering). • Optimux-4E1L operates opposite an Optimux-4E1 standalone unit or an Optimux-4E1 card for the LRS-24 19” rack with central SNMP management. This option provides a compact, cost-effective central solution (see Figure 1). FEATURES DESCRIPTION • To facilitate system diagnostics, Optimux-4E1L features LED status • Optimux-4E1L is a multiplexer • Multiplexes four E1 channels indicators, AIS alarm generation, that combines up to four E1 over a single E2 link recognition, and dry contact channels over a single coax or closure upon link failure. • E2 transmission over coax or fiber optic E2 link. A pair of fiber optic cable • Configuration, monitoring and Optimux-4E1L units offers simple maintenance can be performed and low-cost connectivity of four • Operates with various fiber using an ASCII terminal or a SLIP E1 channels at distances of up to interfaces: connection to an SNMP 120 km/74 miles (see Figure 2). � management station.
